update tests to be specific about the versions they are testing

When setting up tests, you want to rely on your own scheme.  This eliminates coupling to floating versions which gives unnecessary flexibility in most cases and prevents testing all the versions you need.

Cache preferred resources, use in kubectl resource name autocomplete

Fixes #63145
Fixes https://github.com/kubernetes/kubectl/issues/357
Alternative to #61928

* allows indicating a cached list of resources is acceptable when calling `kubectl api-resources` (default is still to rediscover)

kubelet: volume: do not create event on mount success

xref https://github.com/openshift/origin/issues/19497

There is an argument to be made that we should not emit events on volume mount successes.  Many pods have lots of volumes that generate lots of events, especially if the pods are short lived (batch, etc). This creates load on the API server and add noise in the events.

Creating events on volume mount failures is obviously a good idea.  Seems like the absence of such events or the "Started container" event implies mount success for all volumes.

don't block creation on lack of delete powers

Create and delete aren't the same thing, but the alternatives seem worse. This stops checking for deletion powers on create.  You still have to know the UID to create an effective ownerref, so name hunting is unrealistic.

stop using Info.Mappings when they may not be present

On a resource builder, you cannot logically have a RESTMapping or a Client if you're running a local action.  Reliance on the `info.Client` and `info.Mapping` is a bug we need to fix.  This updates the docs and eliminates unnecessary reliance.  Other hits I found didn't have `--local` options, so we're safe or had them and and were already broken.  I think we'll be able to help them after making our creation flow obvious.

Add support for CNI on Windows Server 2016 RTM

**What this PR does / why we need it**:
Windows Server 2016 RTM has limited CNI support. This PR makes it possible for the CNI plugin to be used to setup POD networking on Windows Server 2016 RTM (build number 14393).

Fixes #61939

**Special notes for your reviewer**:
The old mode is not supported and tested on Windows Server 2016 RTM. This change allows the CNI plugin to be used on Windows Server 2016 RTM to retrieve the container IP instead of using workarounds (docker inspect).

CNI support has been added for Windows Server 2016 version 1709 (build number 16299), this patch will just allow the same support for older build numbers.

Windows Server 2016 RTM has a longer lifecycle (LTS) than Windows Server 2016 version 1709.

Use a []string for CgroupName, which is a more accurate internal representation

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

This is purely a refactoring and should bring no essential change in behavior.

It does clarify the cgroup handling code quite a bit.

It is preparation for further changes we might want to do in the cgroup hierarchy. (But it's useful on its own, so even if we don't do any, it should still be considered.)

**Special notes for your reviewer**:

The slice of strings more precisely captures the hierarchic nature of the cgroup paths we use to represent pods and their groupings.

It also ensures we're reducing the chances of passing an incorrect path format to a cgroup driver that requires a different path naming, since now explicit conversions are always needed.

The new constructor `NewCgroupName` starts from an existing `CgroupName`, which enforces a hierarchy where a root is always needed. It also performs checking on the component names to ensure invalid characters ("/" and "_") are not in use.

A `RootCgroupName` for the top of the cgroup hierarchy tree is introduced.

This refactor results in a net reduction of around 30 lines of code,
mainly with the demise of ConvertCgroupNameToSystemd which had fairly
complicated logic in it and was doing just too many things.

There's a small TODO in a helper `updateSystemdCgroupInfo` that was introduced to make this commit possible. That logic really belongs in libcontainer, I'm planning to send a PR there to include it there. (The API already takes a field with that information, only that field is only processed in cgroupfs and not systemd driver, we should fix that.)

Tested: By running the e2e-node tests on both Ubuntu 16.04 (with cgroupfs driver) and CentOS 7 (with systemd driver.)

**NOTE**: I only tested this with dockershim, we should double-check that this works with the CRI endpoints too, both in cgroupfs and systemd modes.
