GCE - Retrieve subnetwork name/url from gce.conf
**What this PR does / why we need it**:
Features like ILB require specifying the subnetwork if the network is type manual.
**Notes:**
The network URL can be [constructed](68e7e18698/pkg/cloudprovider/providers/gce/gce.go (L211-L217)) by fetching instance metadata; however, the subnetwork is not provided through this feature. Users must specify the subnetwork name/url through the gce.conf.
Although multiple subnets can exist in the same region for a network, the cloud provider will only use one subnet url for creating LBs.

Detect cohabitating resources in etcd storage test
**What this PR does / why we need it**:
This change updates the etcd storage path test to detect cohabitating resources by looking at their expected location in etcd. This was not detected in the past because the GVK check did not span across groups.
To limit noise from failures caused by multiple objects at the same location in etcd, the test now fails when different GVRs share the same expected path. Thus every object is expected to have a unique path.

Move docker validation test to separate project.
Docker validation test is leaking VMs because new docker version `DOCKER_VERSION=17.05.0-c` totally breaks the new gci image `GCE_IMAGES=gci-test-60-9579-0-0` with the `gci-docker-version` metadata specified.
The test successfully created the instance, but timed out when checking VM aliveness, and leaked the VM.
I've cleaned up all leaked VMs. This PR moves docker validation node e2e test into a separate project to not influencing other node e2e test.

Fix in-cluster kubectl --namespace override
**What this PR does / why we need it**:
Before this change, if the config was empty, ConfirmUsable() would
return an "invalid configuration" error instead of examining and
honoring the value of the --namespace flag. This change looks at the
overrides first, and returns the overridden value if it exists before
attempting to check if the config is usable. This is most applicable to
in-cluster clients, where they don't have a kubeconfig but they do have
a token and can use KUBERNETES_SERVICE_HOST/_PORT.

oidc client plugin: reduce round trips and fix scopes requested
This PR attempts to simplify the OpenID Connect client plugin to
reduce round trips. The steps taken by the client are now:
* If ID Token isn't expired:
* Do nothing.
* If ID Token is expired:
* Query /.well-known discovery URL to find token_endpoint.
* Use an OAuth2 client and refresh token to request new ID token.
This avoids the previous pattern of always initializing a client,
which would hit the /.well-known endpoint several times.
The client no longer does token validation since the server already
does this. As a result, this code no longer imports
github.com/coreos/go-oidc, instead just using golang.org/x/oauth2
for refreshing.
Overall reduction in tests because we're not verify as many things
on the client side. For example, we're no longer validating the
id_token signature (again, because it's being done on the server
side).
This has been manually tested against dex, and I hope to continue
to test this over the 1.7 release cycle.

clear init container status annotations when cleared in status
When I pod with an init container is terminated due to exceeding its active deadline, the pod status is phase `Failed` with reason `DeadlineExceeded`. All container statuses are cleared from the pod status.
With init containers, however, the status is being regenerated from the status annotations. This is causing kubectl to report the pod state as `Init:0/1` instead of `DeadlineExceeded` because the kubectl printer observes a running init container, which in reality is not running.
This PR clears out the init container status annotations when they have been removed from the pod status so they are not regenerated on the apiserver.

Fix provisioned GCE PD not being reused if already exists
@jsafrane PTAL
This is another attempt at https://github.com/kubernetes/kubernetes/pull/38702 . We have observed that `gce.service.Disks.Insert(gce.projectID, zone, diskToCreate).Do()` instantly gets an error response of alreadyExists, so we must check for it.
I am not sure if we still need to check for the error after `waitForZoneOp`; I think that if there is an alreadyExists error, the `Do()` above will always respond with it instantly. But because I'm not sure, and to be safe, I will leave it.

Only retrieve relevant volumes
**What this PR does / why we need it**:
Improves performance for Cinder volume attach/detach calls.
Currently when Cinder volumes are attached or detached, functions try to retrieve details about the volume from the Nova API. Because some only have the volume name not its UUID, they use the list function in gophercloud to iterate over all volumes to find a match. This incurs severe performance problems on OpenStack projects with lots of volumes (sometimes thousands) since it needs to send a new request when the current page does not contain a match. A better way of doing this is use the `?name=XXX` query parameter to refine the results.
**Which issue this PR fixes**:
https://github.com/kubernetes/kubernetes/issues/26404
**Special notes for your reviewer**:
There were 2 ways of addressing this problem:
1. Use the `name` query parameter
2. Instead of using the list function, switch to using volume UUIDs and use the GET function instead. You'd need to change the signature of a few functions though, such as [`DeleteVolume`](https://github.com/kubernetes/kubernetes/blob/master/pkg/volume/cinder/cinder.go#L49), so I'm not sure how backwards compatible that is.
Since #1 does effectively the same as #2, I went with it because it ensures BC.
One assumption that is made is that the `volumeName` being retrieved matches exactly the name of the volume in Cinder. I'm not sure how accurate that is, but I see no reason why cloud providers would want to append/prefix things arbitrarily.
**Release note**:
```release-note
Improves performance of Cinder volume attach/detach operations

apiextensions: add Established condition
This introduces a `Established` condition on `CustomResourceDefinition`s. `Established` means that the resource has become active. A resource is established when all names are accepted initially without a conflict. A resource stays established until deleted, even during a later NameConflict due to changed names. Note that not all names can be changed.
This change is necessary to allow deletion of once-active CRDs which might have still instances, but have NameConflicts now. Before this PR the REST endpoint was not active anymore in this case, making deletion of the instances impossible.
An admin wants to specify in which AWS availability zone(s) users may create persistent volumes using dynamic provisioning.
That's why the admin can now configure in StorageClass object a comma separated list of zones. Dynamically created PVs for PVCs that use the StorageClass are created in one of the configured zones.
