Make kubelet `ReadLogs` backward compatible.

`containerLogPathLabelKey` label was added in dockershim since 1.5. https://github.com/kubernetes/kubernetes/commit/121a91eb12a186640c634266e5d190c3ecd7f527

ContainerStatus.LogPath was added since Kubernetes 1.7. https://github.com/kubernetes/kubernetes/commit/c3b52267ca615e1efca70e47f24a39bfcab321cc

I believe it is safe to reply on this field without backward compatibility issue. And `crictl` is using it as well https://github.com/kubernetes-incubator/cri-tools/blob/master/cmd/crictl/logs.go#L88.

With this change, in the future, kubelet `ReadLogs` will be backward compatible as long as the log format is backward compatible.

Add name output and verb filtering to api-resources

This allows `kubectl api-resources -o name` to be used as input to `kubectl get ...`

to see all resources still existing in a given namespace:

Example:
```sh
kubectl api-resources --verbs=list --namespaced -o name | xargs -n 1 kubectl get -o name -n foo
```

Release note:
```release-note
`kubectl api-resources` now supports filtering to resources supporting specific verbs, and can output fully qualified resource names suitable for combining with commands like `kubectl get`

kubelet: logs: do not wait when following terminated container

Currently, a `kubectl logs -f` on a terminated container will output the logs, wait 5 seconds (`stateCheckPeriod`), then return.  The 5 seconds delay should not occur as the container is terminated and unable to generate additional log messages.

This PR puts a check at the beginning of `waitLogs()` to avoid doing the wait when the container is not running.

divide statically known typer from dynamically derived restmapper

The CLI factory conflated a statically known typer and a dynamically derived restmapper. This produced confusion and unnecessary indirection.  This pull separates dynamically known from statically known.

A future pull will continue the separation of in the builder to indicate the points of variability for clients, which should logically be limited to a negotiated serializer for decoding and an object typer.

Bump QPS on namespace controller

https://github.com/kubernetes/kubernetes/pull/62913 switched from using a client pool, where each groupVersionResource got its own rest client, to a single client.

Improve Azure disk operations for vmas and vmss

**What this PR does / why we need it**:

Today, VirtualMachineScaleSetVM and VirtualMachine are different data structures (because of different API versions), so the disk attach operation seems duplicate between vm and vmss. That means although disk operations are in same logic, some duplication is required then.

With #63063, they are using the same API now. This PR improves Azure disk operations by adding another `GetDataDisks()` interface in vmSet and moving common logics to controllerCommon.
