Fix an unreachable kubectl explain field lookup test
In error case, the condition `gotErr != test.err && gotPath !=
test.expectedPath` never fulfill because in this case both gotPath and
test.expectedPath are always an empty string. So the err “err: `field "what?"
does not exist`” doesn’t get tasted. For example, if you change the value of
`err:` to anything, the test still will pass. Also, since gotPath is empty
string in case of err, in the output error we probably don’t want to display
path.

When calling GKE API andd gcloud, take into account
that clusters can be regional.
This currently uses MultiZonal as an indicator that
cluster is regional, which is suboptimal, but considering
that our tests do not work with multizonal clusters
at the moment, there is no regression.
This should be changed once there is an indicator available
that the cluster is regional.
- GroupNames are domain-like logical name for the group. Only the
first segment is used as default for GoName
- PkgName is the directory name. All packages in client, informer, lister
re-use this for packages.
- GoName is the Go identifier (CamelCase) used to reference the group, e.g.
in the interface names, in the clientsets etc. Moreover it is used
for package import aliases.
The GoName defaults to the first segment of the GroupName.

Added service annotation to set Azure DNS label for public IP
**What this PR does / why we need it**: Added a feature to set the DNS label for public IPs in the Azure cloud.
For example:
```
apiVersion: v1
kind: Service
metadata:
annotations:
service.alpha.kubernetes.io/label-name: myservice
...
```
Will resolve myservice.westus.cloudapp.azure.com to the service's IP.
**Which issue this PR fixes**: fixes#44775
**Special notes for your reviewer**: Note that this is defining a new annotation, so feel free to point out if there is a preferred convention or anything else that needs to be done.
**Release note**:
```release-note
New service annotation "service.beta.kubernetes.io/azure-dns-label-name" to set Azure DNS label name for public IP

[Part 1] Remove docker dep in kubelet startup
**What this PR does / why we need it**:
Remove dependency of docker during kubelet start up.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*:
Part 1 of #54090
**Special notes for your reviewer**:
Changes include:
1. Move docker client initialization into dockershim pkg.
2. Pass a docker `ClientConfig` from kubelet to dockershim
3. Pass parameters needed by `FakeDockerClient` thru `ClientConfig` to dockershim
(TODO, the second part) Make dockershim tolerate when dockerd is down, otherwise it will still fail kubelet
Please note after this PR, kubelet will still fail if dockerd is down, this will be fixed in the subsequent PR by making dockershim tolerate dockerd failure (initializing docker client in a separate goroutine), and refactoring cgroup and log driver detection.
**Release note**:
```release-note
Remove docker dependency during kubelet start up

Make sure that storage request of pvc is not zero
I do not know whether we should add the checking zero logic to `ValidateResourceQuantityValue`.
But at lease we should do this when validate PVC. If PVC requests 0Gi storage,it does not make sense to provision that volume.
Volume plugins will not check whether the request of PVC is 0 when they run `CreateVolume` or `CreateImage` called by `Provision()`

Replace sets.List() with sets.UnsortedList() in pkg/proxy

Fix .git rsync filter for prow
**What this PR does / why we need it**:
The prow bootstrap job uses the [`--separate-git-dir`](https://git-scm.com/docs/git-init#git-init---separate-git-dirltgitdirgt) flag when cloning the target repo. This leaves a text file named `./.git` containing the path to the git dir instead of the typical `./.git/` directory right in the working tree.
This modifies the rsync filter to filter out this file *or* directory, so that jobs that use the build container system aren't tripped up by a text file that points to a directory that doesn't exist in the build container system.
