Kubeadm - Make code OS-agnostic

**What this PR does / why we need it**:
Kubernetes just got Windows Containers alpha support, opening the opportunity for kubeadm to also be used to setup, at least, Windows Server 2016 or newer worker nodes. With that in mind, we should take the effort of writing OS-agnostic code whenever possible, e.g. when dealing with the filesystem.

no-snat test

This test checks that Pods can communicate with each other in the same cluster without SNAT.

I intend to create a job that runs this in small clusters (\~3 nodes) at a low frequency (\~once per day) so that we have a signal as we work on allowing multiple non-masquerade CIDRs to be configured (see [kubernetes-incubator/ip-masq-agent](https://github.com/kubernetes-incubator/ip-masq-agent), for example).

apiextensions: add integration test for name conflicts

**What this PR does / why we need it**: Add integration test for name conflicts.
Create 2 CRDs with name conflict. The controller sets the NameConflict condition on the second one. Delete the first one. The second CRD should now get accepted.

Update:
- [x] Add integration test for name conflicts
- [x] Fix naming controller so that when a resource is deleted, other resources in the same group are added to the queue
- [x]  Add integration test for self link (cluster scoped resources)
- [x] Add bigger poll interval
- [x] Fix DeleteCustomResourceDefinition poll condition

Fix the bug: If there is sth wrong to run hollow kubelet, kubemark will just hang instead of exiting.

* Reviewed or merged at least 30 PRs to the codebase
[k82cn]: 71 merged PRs in kubernetes/kubernetes, and ~100 PRs in kuberentes at https://goo.gl/j2D1fR

As an approver,

GCE - Refactor API for firewall and backend service creation

**What this PR does / why we need it**:
 - Currently, firewall creation function actually instantiates the firewall object; this is inconsistent with the rest of GCE api calls. The API normally gets passed in an existing object.
 - Necessary information for firewall creation, (`computeHostTags`,`nodeTags`,`networkURL`,`subnetworkURL`,`region`) were private to within the package. These now have public getters.
 - Consumers might need to know whether the cluster is running on a cross-project network. A new `OnXPN` func will make that information available.
 - Backend services for regions have been added. Global ones have been renamed to specify global. 
 - NamedPort management of instance groups has been changed from an `AddPortsToInstanceGroup` func (and missing complementary `Remove...`) to a single, simple `SetNamedPortsOfInstanceGroup`
 - Addressed nitpick review comments of #45524 

ILB needs the regional backend services and firewall refactor.  The ingress controller needs the new `OnXPN` func to decide whether to create a firewall.

Remove deletecollection support from namespace object

Namespace storage accidentally picked up deletecollection support from embedding the generic store. If invoked, it skips the custom namespace `Delete()` storage method that enforces finalization, and skips the namespace lifecycle admission plugin that protects immortal namespaces from deletion.

Given the data integrity implications of skipping namespace finalization, I'd backport this as far as we're releasing patch releases.

```release-note
The namespace API object no longer supports the deletecollection operation.

Move NetworkPolicy to v1

Move NetworkPolicy to v1

@kubernetes/sig-network-misc 

**Release note**:
```release-note
NetworkPolicy has been moved from `extensions/v1beta1` to the new
`networking.k8s.io/v1` API group. The structure remains unchanged from
the beta1 API.

The `net.beta.kubernetes.io/network-policy` annotation on Namespaces
to opt in to isolation has been removed. Instead, isolation is now
determined at a per-pod level, with pods being isolated if there is
any NetworkPolicy whose spec.podSelector targets them. Pods that are
targeted by NetworkPolicies accept traffic that is accepted by any of
the NetworkPolicies (and nothing else), and pods that are not targeted
by any NetworkPolicy accept all traffic by default.

Action Required:

When upgrading to Kubernetes 1.7 (and a network plugin that supports
the new NetworkPolicy v1 semantics), to ensure full behavioral
compatibility with v1beta1:

    1. In Namespaces that previously had the "DefaultDeny" annotation,
       you can create equivalent v1 semantics by creating a
       NetworkPolicy that matches all pods but does not allow any
       traffic:

           kind: NetworkPolicy
           apiVersion: networking.k8s.io/v1
           metadata:
             name: default-deny
           spec:
             podSelector:

       This will ensure that pods that aren't match by any other
       NetworkPolicy will continue to be fully-isolated, as they were
       before.

    2. In Namespaces that previously did not have the "DefaultDeny"
       annotation, you should delete any existing NetworkPolicy
       objects. These would have had no effect before, but with v1
       semantics they might cause some traffic to be blocked that you
       didn't intend to be blocked.
