Use actual hostname when creating network e2e test pod

**What this PR does / why we need it**:
This changes a e2e framework network test Pod use the actual hostname value to match the `kubernetes.io/hostname` label in it's `NodeSelector`. Currently it assumes the Node name will match that hostname label which is not true in all environments.

Audit webhook config for GCE

Add a `ADVANCED_AUDIT_BACKEND` (comma delimited list) environment variable to the GCE cluster config to select the audit backend, and add configuration for the webhook backend.

~~Based on the first commit from https://github.com/kubernetes/kubernetes/pull/46557~~

For kubernetes/features#22

Since this is GCE-only configuration plumbing, I think this should be exempt from code-freeze.

Remove Initializers from admission-control in kubernetes-master charm for pre-1.7

**What this PR does / why we need it**:

This fixes a problem with the kubernetes-master charm where kube-apiserver never comes up:

```
failed to initialize admission: Unknown admission plugin: Initializers
```

The Initializers plugin does not exist before Kubernetes 1.7. The charm needs to support 1.6 as well.

Fixes 47182

**What this PR does / why we need it**: Adds some state guards to the idle_status message to speed up the deployment

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #47182

**Special notes for your reviewer**:
This adds additional state guards of  the idle_status method, which will
prevent it from being run until a worker has joined the relationship.
Previous invocations may have some messaging inconsistencies but will reach
eventual consistency once a worker has joined.

This prevents the polling loop from executing too soon, bloating the
installation time by bare-minimum an additional 10 minutes.

**Release note**:

```release-note
Added state guards to the idle_status messaging in the kubernetes-master charm to make deployment faster on initial deployment.

kubeadm: Enable the Node Authorizer/Admission plugin in v1.7

**What this PR does / why we need it**:

This is similar to https://github.com/kubernetes/kubernetes/pull/46796, but for kubeadm.
Basically it was a part of https://github.com/kubernetes/kubernetes/pull/46796, but there were some other upgradability and compability concerns for kubeadm I took care of while working today.

Example:

```console
$ kubeadm init --kubernetes-version v1.7.0-beta.0
[kubeadm] WARNING: kubeadm is in beta, please do not use it for production clusters.
[init] Using Kubernetes version: v1.7.0-beta.0
[init] Using Authorization mode: [RBAC Node]
...
$ sudo kubectl --kubeconfig=/etc/kubernetes/kubelet.conf get secret foo
Error from server (Forbidden): User "system:node:thegopher" cannot get secrets in the namespace "default".: "no path found to object" (get secrets foo)

$ echo '{"apiVersion":"v1","kind":"Node","metadata":{"name":"foo"}}' | sudo kubectl create -f - --kubeconfig=/etc/kubernetes/kubelet.conf
Error from server (Forbidden): error when creating "STDIN": nodes "foo" is forbidden: node thegopher cannot modify node foo
```

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #

**Special notes for your reviewer**:

Depends on https://github.com/kubernetes/kubernetes/pull/46864 (uses that PR as a base, will rebase once it's merged)

Please only review the second commit. Will also fix tests in a minute.

Support windows in dockershim

**What this PR does / why we need it**:
This is the 2nd part for https://github.com/kubernetes/kubernetes/issues/45927 .

The non-cri implementation dockertools was removed from kubelet v1.7 .
Part of previous work for supporting windows container lies in v1.6 dockertools, this PR is to port them to dockershim.

Main reference file in v1.6 dockertools windows support:
https://github.com/kubernetes/kubernetes/blob/v1.6.4/pkg/kubelet/dockertools/docker_manager_windows.go

**Which issue this PR fixes**
45927, for now catching up the implementation of v1.6

**Special notes for your reviewer**:
The code change includes 4 parts, put them together as we discussed in https://github.com/kubernetes/kubernetes/pull/46089

1. Update go-winio package to a newer version
  'go-winio' package is used by docker client.
  This change is to bring the support for Go v1.8, specifically included in the PR: https://github.com/Microsoft/go-winio/pull/48 
Otherwise it will produce a lot of error like in: https://github.com/fsouza/go-dockerclient/issues/648 

2. Add os dependent getSecurityOpts helper method. 
seccomp not supported on windows
  Corresponding code in v1.6: https://github.com/kubernetes/kubernetes/blob/v1.6.4/pkg/kubelet/dockertools/docker_manager_windows.go#L78

3. Add updateCreateConfig.
Allow user specified network mode setting. This is to be compatible with what kube-proxy package does on Windows. 
  Also, there is a Linux section in both sandbox config and container config： LinuxPodSandboxConfig， LinuxContainerConfig.
And that section later goes to Config and HostConfig section under docker container createConfig. Ideally hostconfig section should be dependent on host os, while config should depend on container image os.
  To simplify the case, here it assumes that windows host supports windows type container image only. It needs to be updated when kubernetes is to support windows host running linux container image or the like.
  Corresponding code in v1.6: https://github.com/kubernetes/kubernetes/blob/v1.6.4/pkg/kubelet/dockertools/docker_manager_windows.go#L57

4. Add podIpCache in dockershim. 
  For v1.6 windows implementation, it still does not use sandbox, thus only allow single container to be exposed.
  Here added a cache for saving container IP, to get adapted to the new CRI api.
Corresponding code in v1.6:
No sandbox: https://github.com/kubernetes/kubernetes/blob/v1.6.4/pkg/kubelet/dockertools/docker_manager_windows.go#L66
Use container id as pod ip: https://github.com/kubernetes/kubernetes/blob/v1.6.4/pkg/kubelet/dockertools/docker_manager.go#L2727

Add a secretbox and AES-CBC path for encrypt at rest

Add a secretbox and AES-CBC encrypt at rest provider and alter the config, based on feedback from security review.  AES-CBC is more well reviewed and generally fits better with common criteria and FIPS, secretbox is newer and faster than CBC.

```release-note
Add secretbox and AES-CBC encryption modes to at rest encryption.  AES-CBC is considered superior to AES-GCM because it is resistant to nonce-reuse attacks, and secretbox uses Poly1305 and XSalsa20.

DeleteCollection should include uninitialized resources

Users who delete a collection expect all resources to be deleted, and
users can also delete an uninitialized resource. To preserve this
expectation, DeleteCollection selects all resources regardless of
initialization.

The namespace controller should list uninitialized resources in order to
gate cleanup of a namespace.

Fixes #47137

HPA: only send updates when the status has changed

This commit only sends updates if the status has actually changed.
Since the HPA runs at a regular interval, this should reduce the volume
of writes, especially on short HPA intervals with relatively constant
metrics.

Fixes #47077

**Release note**:
```release-note
The HorizontalPodAutoscaler controller will now only send updates when it has new status information, reducing the number of writes caused by the controller.

Remove duplicate errors from an aggregate error input.

This PR, in general, removes duplicate errors from an aggregate error input, and returns unique errors with their occurrence count. Specifically,  this PR helps with some scheduler errors that fill the log enormously. For example, see the following `truncated` output from a 300-plus nodes cluster, as there was a same error from almost all nodes.


[SchedulerPredicates failed due to persistentvolumeclaims "mongodb" not found, which is unexpected., SchedulerPredicates failed due to persistentvolumeclaims "mongodb" not found, which is unexpected., SchedulerPredicates failed due to persistentvolumeclaims "mongodb" not found, which is unexpected., SchedulerPredicates failed due to persistentvolumeclaims "mongodb" not found, which is unexpected., SchedulerPredicates failed due to persistentvolumeclaims "mongodb" not found, which is unexpected., SchedulerPredicates failed due to persistentvolumeclaims "mongodb" not found, which is unexpected., SchedulerPredicates failed due to persistentvolumeclaims "mongodb" not found, which is unexpected., SchedulerPredicates failed due to persistentvolumeclaims "mongodb" not found, which is unexpected., SchedulerPredicates failed due to persistentvolumeclaims "mongodb" not found, which is unexpected., SchedulerPredicates failed due to persistentvolumeclaims "mongodb" not found, which is unexpected., SchedulerPredicates failed due to persistentvolumeclaims "mongodb" not found, which is unexpected., SchedulerPredicates failed due to persistentvolumeclaims "mongodb" not found, which is unexpected., SchedulerPredicates failed due to persistentvolumeclaims "mongodb" not found, which is unexpected., SchedulerPredicates failed due to persistentvolumeclaims "mongodb" not found, which is unexpected., SchedulerPredicates failed due to persistentvolumeclaims "mongodb" not found, which is unexpected., SchedulerPredicates failed due to persistentvolumeclaims "mongodb" not found, which is unexpected., SchedulerPredicates failed due to persistentvolumeclaims "mongodb" not found, which is unexpected., SchedulerPredicates failed due to persistentvolumeclaims "mongodb" not found.........

gpusInUse info error when kubelet restarts

**What this PR does / why we need it**:
In my test, I found 2 errors in the nvidia_gpu_manager.go.
1. the number of activePods in gpusInUse() equals to 0 when kubelet restarts. It seems the Start() method was called before pods recovery which caused this error. So I decide not to call gpusInUse() in the Start() function, just let it happen when new pod needs to be created.
2. the container.ContainerID in line 242 returns the id in format of "docker://<container_id>", this will make the client failed to inspect the container by id. We have to erase the prefix of "docker://".

**Special notes for your reviewer**:

**Release note**:

```
Avoid assigning the same GPU to multiple containers.
```

update NetworkPolicy e2e test for v1 semantics

This makes the NetworkPolicy test at least correct for v1, although ideally we'll eventually add a few more tests... (So this covers about half of #46625.)

I've tested that this compiles, but not that it passes, since I don't have a v1-compatible NetworkPolicy implementation yet...
