[kubelet] Auto-discover node IP if neither cloud provider exists and IP is not explicitly specified
One example where the earlier implementation failed is when running kubelet on CoreOS (bare-metal), where the nameserver is set to `8.8.8.8`. kubelet tries to lookup the node name agains Google DNS, which obviously fails. The kubelet won't recover after that.
The workaround hsa been to set `--hostname-override` to an IP address, but it's quite annoying to try to make a multi-distro way of getting the IP in bash for example. This way is much cleaner.
Refactored the function a little bit at the same time

Verify volume.GetPath() never returns ""
Add a new helper method volume.GetPath(Mounter) instead of calling
the GetPath() of the Mounter directly. Check if GetPath() is returning
a "" and convert that into an error.

kubectl config set-crentials: add arguments for auth providers
This PR adds `--auth-provider` and `--auth-provider-arg` flags to the
`kubectl config set-credentials` sub-command.
There's currently no way of interacting with the new auth provider framework added in #23066 through kubectl. You have to render a custom kubeconfig to use them. Additionally `kubectl config set` just sort of craps out when attempting to interact with authentication info objects (#29312).
This is a minimal implementation of allowing `kubect config set-credentials` to set fields for client auth providers.

Run goimport for the whole repo
While removing GOMAXPROC and running goimports, I noticed quite a lot of other files also needed a goimport format. Didn't commit `*.generated.go`, `*.deepcopy.go` or files in `vendor`
This is more for testing if it builds.
The only strange thing here is the gopkg.in/gcfg.v1 => github.com/scalingdata/gcfg replace.

optimize conditions of ServiceReplenishmentUpdateFunc to replenish service
Originally, the replenishQuota method didn't focus on the third parameter object even if others transfered to it, i think the function is not efficient and perfect. then i use the third param to get MatchResources, it will be more exact. for example, if the old pod was quota tracked and the new was not, the replenishQuota only focus on usage resource of the old pod, still if the third parameter object is nil, the process will be same as before

Fix Incorrect response model for pods/{name}/log
The swagger spec for pods/{name}/log does not include
"text/plain" as a possible content-type for the the response.
So we implement ProducesMIMETypes to make sure "text/plain"
gets added to the default list ot content-types.
the v1.json was generated by running:
hack/update-generated-swagger-docs.sh;./hack/update-swagger-spec.sh;

make reousrce prefix consistent with other registries
Storage class registry was added recently in #29694.
In other registries, resource prefix was changed to a more generic way using RESTOptions.ResourcePrefix.

refactor quota calculation for re-use
Refactors quota calculation to allow reuse. This will allow us to do "punch through" calculation inside of admission if a particular quota needs usage stats and allows downstream re-use by moving calculation closer to the evaluators and separating "needs calculation" logic from "do calculation".

Rewrite service controller to apply best controller pattern
This PR is a long term solution for #21625:
We apply the same pattern like replication controller to service controller to avoid the potential process order messes in service controller, the change includes:
1. introduce informer controller to watch service changes from kube-apiserver, so that every changes on same service will be kept in serviceStore as the only element.
2. put the service name to be processed to working queue
3. when process service, always get info from serviceStore to ensure the info is up-to-date
4. keep the retry mechanism, sleep for certain interval and add it back to queue.
5. remote the logic of reading last service info from kube-apiserver before processing the LB info as we trust the info from serviceStore.
The UT has been passed, manual test passed after I hardcode the cloud provider as FakeCloud, however I am not able to boot a k8s cluster with any available cloudprovider, so e2e test is not done.
Submit this PR first for review and for triggering a e2e test.

fix annotate.go single resource check
```release-note
Fix issue with kubectl annotate when --resource-version is provided.
```
When using `kubectl annotate` with a `--resource-version` on a resource, such as `kubectl annotate pod <pod_name> --resource-version=1820 description='myannotation'`, the command fails with the error: `error: --resource-version may only be used with a single resource`.
Upon printing the output of `resources` that the annotate command receives from cli args, it prints: `Resources:[pod <pod_name>]`. In other words, it treats the name of the resource as a second resource. This PR addresses this issue by using the resource builder `Singular` flag to determine if only a single resource was passed.
