CRI: Fix StopContainer timeout

Fixes https://github.com/kubernetes/kubernetes/issues/44956.

I verified this PR with the example provided in https://github.com/kubernetes/kubernetes/issues/44956, and now pod deletion will respect grace period timeout:
```
NAME                         READY     STATUS        RESTARTS   AGE
gracefully-terminating-pod   1/1       Terminating   0          6m
```

Allow Partial Success for ImageGC

Fixes #44951.  When the eviction manager is under disk pressure, it first attempts to reclaim disk space by deleting images.  However, if there are any errors during the image deletion process, the eviction manager treats that as a failed attempt delete images--even if some were successfully deleted.

This change essentially makes the eviction manager ignore errors during image garbage collection, and instead rely solely on the quantity of resources reclaimed.  If image deletion completely fails, for example, then this should still work as it would return 0 bytes freed.  This allows for partial success, because any resources freed are counted, regardless of if some images fail to be deleted, for example.

This does not require any changes to the image manager, as the current behavior is already to return the disk space freed along with any errors.

```release-note
Fixes a bug where pods were evicted even after images are successfully deleted.
```

apimachinery/pkg/util/wait: Fix potential goroutine leak in pollInternal().

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

Without the change, the wait function wouldn't exit until the timeout
happens, so if the timeout is set to a big value and the Poll() is run
inside a loop, then the total goroutines will increase indefinitely.

This PR fixes the issue by closing the stop channel to tell the wait function
to exit immediately if condition is true or any error happens.

Remove import of internal api package in generated external-versioned listers

Follow up of https://github.com/kubernetes/kubernetes/pull/44523

One line change in cmd/libs/go2idl/lister-gen/generators/lister.go, and simple changes in pkg/apis/autoscaling/v2alpha1/register.go, other changes are generated.

The internal api package will be eliminated from client-go, so these imports should be removed. Also, it's more correct to report the versioned resource in the error.

e2e tests for VSAN policy support in Kubernetes for vSphere

Following e2e test cases have been implemented for VSAN policy support in Kubernetes for vSphere. These e2e tests are for PR #42974 which out for review.

A total of 8 test cases for below mentioned 5 different scenarios are implemented.

Test cases:

1. Validation of VSAN capabilities.
- hostFailuresToTolerate : Minimum 1 and Max 3. Should be integer.
- stripeWidth: Minimum is 1 and Maximum is 12. Should be integer.
- proportionalCapacity: Expressed in percentage. Should be between 0 and 100. Should be integer.
- iopsLimit: Should be greater than 0. Should be integer.

2. Use a VSAN testbed setup. Try valid VSAN capabilities which are supported by VSAN testbed. Make sure the disk is created with policy configured with it.
- Ex: Using hostFailuresToTolerate=0 and cacheReservation=12
Ex: diskStripes=1 and objectSpaceReservation=30

3. Use a VSAN testbed setup. Try valid VSAN capabilities which are not supported by VSAN testbed. Make sure that the disk creation fails and PVC status is pending.

4. Try using VSAN capabilities on a non-VSAN datastore. PVC status will be pending and it errors to the user saying to VSAN capabilities are not supported on a non-VSAN testbed.

5. Try all 1 to 5 with custom datastore specified by the user.

Fixes #43461

**What this PR does / why we need it**:
The master-components started state triggers a daemon recycle. The guard
was to prevent the daemons from being cycled too often and interrupting
normal workflow. This additional state check is probing the etcd
connection and if changing triggers a re-configure and recycle of the api-control 
plane when etcd units are scaling up and down.

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #43461

**Special notes for your reviewer**:
Check the contents of /var/snap/kube-apiserver/current/args after scaling etcd both up and down and the values will have changed, and kube-apiserver will have recycled to read the new connection string.

**Release note**:

```release-note
kubernetes-master juju charm properly detects etcd-scale events and reconfigures appropriately.
```

Add redirect support to SpdyRoundTripper

Add support for following redirects to the SpdyRoundTripper. This is
necessary for clients using it directly (e.g. the apiserver talking
directly to the kubelet) because the CRI streaming server issues a
redirect for streaming requests.

We need this in OpenShift because we have code that executes inside our apiserver that talks directly to the node to perform an attach request, and we need to be able to follow that redirect.

This code was adapted from the upgrade-aware proxy handler.

e2e-node: refactor lifecycle test to avoid selinux issues

Fixes #42905

Previously, the exec hook tests mounted a HostPath volume from /tmp and touched a file as a indicator that the hook had run.  This is prohibited by selinux policy on Fedora/RHEL/Centos.

This PR refactors the test to avoid filesystem indication and use the same indication that the HTTP hooks use; a GET to a http endpoint.  The exec hooks run `curl` to hit this endpoint and trigger the indication.  This simplifies this test quite a bit as well, removing over 85 lines of code.

REVIEWER NOTE: The diff is a mess on this one.  Probably better to just review the new version of the file.

Remove misleading error from CronJob controller when it can't find parent UID

CronJob controller lists all `Jobs` and then tries to match then against `CronJobs` using parent UID. It reports error if parent UID can't be found which means it reports error  on every job which is not part of CronJob


```release-note
NONE
```

The master-components started state triggers a daemon recycle. The guard
was to prevent the daemons from being cycled too often and interrupting
normal workflow. This additional state check is guarded against the etcd
connection string from changing, allowing the current behavior but
triggers a re-configure and recycle of the api-control plane when etcd
units are scaling up and down.

Support running Ubuntu image on GCE

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

This PR (on top of #44629) contains the script changes for running Ubuntu image on GCE.

**Special notes for your reviewer**:

We made change in `gci/node.yaml` and `gci/master.yaml` to ensure that Kubernetes jobs can start automatically after reboot. This is not needed for GCI but required by Ubuntu. See https://github.com/kubernetes/kubernetes/pull/44744#discussion_r113105970 for details. With this change, Ubuntu could use the same provisioning scripts as GCI's.

Ran e2e tests using the following command and all tests passed.

```
KUBE_GCE_NODE_IMAGE=ubuntu-gke-1604-xenial-v20170420-1 KUBE_GCE_NODE_PROJECT=ubuntu-os-gke-cloud KUBE_NODE_OS_DISTRIBUTION=ubuntu GINKGO_PARALLEL=y GINKGO_PARALLEL_NODES=30 go run hack/e2e.go -- -v --build --up --test --test_args="--ginkgo.skip=\[Slow\]|\[Serial\]|\[Disruptive\]|\[Flaky\]|\[Feature:.+\]" --down
```

Also tested manually for both GCI and Ubuntu images.

**Release note**:
`Support Ubuntu 16.04 image on GCE`
