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.

NONE

Add Simplified Chinese translation for kubectl
What this PR does / why we need it:
This PR provides first attempt to translate kubectl in Simplified Chinese.

No issues
Special notes for your reviewer:
Although I'm a native speaker for Mandarin Chinese, but I think translation is a whole different knowledge which I'm not good at it, so this pr absolutely need to be polished.
@adohe @mengqiy @resouer @k82cn @caesarxuchao @wanghaoran1988 sorry I think there are so many folks who are good at Chinese I haven't mention, feel free to leave a comment on it : )

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

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.

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.
The zone parameter provided in a Storage Class may erroneously be an empty string or contain only spaces and tab characters. Such situation shall be detected and reported as an error.
That's why the func ValidateZone was added.
An admin shall be able to configure a comma separated list of zones for a StorageClass.
That's why the func ZonesToSet (string) (set.String, error) is added. The func ZonesToSet converts a string containing a comma separated list of zones to a set. In case the list contains an empty zone an error is returned.

GC: update required verbs for deletable resources, allow list of ignored resources to be customized
The garbage collector controller currently needs to list, watch, get,
patch, update, and delete resources. Update the criteria for
deletable resources to reflect this.
Also allow the list of resources the garbage collector controller should
ignore to be customizable, so downstream integrators can add their own
resources to the list, if necessary.
