Add metrics to all major gce operations (latency, errors)
```release-note
Add metrics to all major gce operations {latency, errors}
The new metrics are:
cloudprovider_gce_api_request_duration_seconds{request, region, zone}
cloudprovider_gce_api_request_errors{request, region, zone}
`request` is the specific function that is used.
`region` is the target region (Will be "<n/a>" if not applicable)
`zone` is the target zone (Will be "<n/a>" if not applicable)
Note: this fixes some issues with the previous implementation of
metrics for disks:
- Time duration tracked was of the initial API call, not the entire
operation.
- Metrics label tuple would have resulted in many independent
histograms stored, one for each disk. (Did not aggregate well).

Optimize the time taken to create Persistent volumes with VSAN storage capabilities at scale and handle VPXD crashes
Currently creating persistent volumes with VSAN storage capabilities at scale is taking very large amount of time. We have tested at the scale of 500-600 PVC's and its more time for all the PVC requests to go from Pending state to Bound state.
- In our current design we use a single systemVM - "kubernetes-helper-vm" as a means to create a persistent volume with the VSAN policy configured.
- Since all the operations are on a single system VM, all requests on scale get queued and executed serially on this system VM. Because of this creating a high number of PVC's is taking very large time.
- Since its a single system VM, all parallel PVC requests most of the time tend to take the same SCSI adapter on the system VM and also same unit number on the SCSI adapter. Therefore the error rate is high.
Inorder to overcome these issues and to optimize the time taken to create persistent volumes with VSAN storage capabilities at scale we have slightly modified the design which is described below:
- In this model, we create a VM on the fly for every persistent volume that is being created. Since all the reconfigure operations to create a disk with the VSAN policy configured are on their individual VM's, all of these PVC's request execute in parallel independent one other.
- With this new design, there will no error rate at all.
Also, we have overcome the problem of vpxd crashes and any other intermediate problems by checking type of the errors.

Fix cockroachdb statefulset test read/write commands
Explicitly specifying `--insecure` is required on insecure clusters,
which started being enforced in a very recent release. In 2 weeks
we'll have a stable image version that we can reliably pin the
relevant statefulset yaml file to in order to avoid stupid failures
like this. I'm really sorry for the flakes!
**What this PR does / why we need it**:
It fixes the currently broken statefulset test suite - https://storage.googleapis.com/k8s-gubernator/triage/index.html?job=gci-gce-statefulset&test=CockroachDB

Update kubernetes-e2e charm to use snaps
**What this PR does / why we need it**:
This updates the kubernetes-e2e charm to use snaps instead of Juju resources for payload delivery.
The main advantage of this is that it decouples the charm from the e2e payload, allowing us to support multiple versions of Kubernetes with a single release of the charm.

Cleanup some of the tarball producing code for e2e node tests
This is some e2e node cleanup work I found sitting in a local branch while deleting old local git branches. It looks like it's still useful.
The new metrics is:

cloudprovider_gce_api_request_errors{request, region, zone}
`request` is the specific function that is used.
`region` is the target region (Will be "<n/a>" if not applicable)

Make metrics filenames for e2e tests indicate the test better
Currently the names of the json files with metrics for e2e tests are named by appending the `SummaryKind` with a timestamp of the test. It took me some time to figure out which file corresponds to which e2e test due to this. Changing it to have the testname instead of the timestamp.

Don't check in zz_generated.openapi.go.
`zz_generated.openapi.go` is the file that causes the most merge conflicts of all. In #33440, @thockin updated the makefile to support generating these files on demand, but that didn't play well with bazel/gazel.
In this PR, I add a new build macro that will generate this file with a `go_genrule`. I added support for keeping the BUILD file up to date in mikedanese/gazel#34.

[Federation][e2e] Fix a failing federation e2e testcase in gce-serial
This is to fix the failing test case in federation [gce-serial](https://k8s-testgrid.appspot.com/cluster-federation#gce-serial) tests. The test case has been failing consistently since we registered the clusters in suite-init instead of doing it in every test case.
Instead of registering and then unregistering, we will be now unregistering and then registering the cluster to federation. this test will be run in serial and will not affect other test cases too.

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.
