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).
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
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.

Add more volume types in e2e and fix part of them.
**What this PR does / why we need it**:
- Add dir-link/dir-bindmounted/dir-link-bindmounted/bockfs volume types for e2e tests.
- Fix fsGroup related e2e tests partially.
- Return error if we cannot resolve volume path.
- Because we should not fallback to volume path, if it's a symbolic link, we may get wrong results.
To safely set fsGroup on local volume, we need to implement these two methods correctly for all volume types both on the host and in container:
- get volume path kubelet can access
- paths on the host and in container are different
- get mount references
- for directories, we cannot use its mount source (device field) to identify mount references, because directories on same filesystem have same mount source (e.g. tmpfs), we need to check filesystem's major:minor and directory root path on it
Here is current status:
| | (A) volume-path (host) | (B) volume-path (container) | (C) mount-refs (host) | (D) mount-refs (container) |
| --- | --- | --- | --- | --- |
| (1) dir | OK | FAIL | FAIL | FAIL |
| (2) dir-link | OK | FAIL | FAIL | FAIL |
| (3) dir-bindmounted | OK | FAIL | FAIL | FAIL |
| (4) dir-link-bindmounted | OK | FAIL | FAIL | FAIL |
| (5) tmpfs| OK | FAIL | FAIL | FAIL |
| (6) blockfs| OK | FAIL | OK | FAIL |
| (7) block| NOTNEEDED | NOTNEEDED | NOTNEEDED | NOTNEEDED |
| (8) gce-localssd-scsi-fs| NOTTESTED | NOTTESTED | NOTTESTED | NOTTESTED |
- This PR uses `nsenter ... readlink` to resolve path in container as @msau42 @jsafrane [suggested](https://github.com/kubernetes/kubernetes/pull/61489#pullrequestreview-110032850). This fixes B1:B6 and D6, , the rest will be addressed in https://github.com/kubernetes/kubernetes/pull/62102.
- C5:D5 marked `FAIL` because `tmpfs` filesystems can share same mount source, we cannot rely on it to check mount references. e2e tests passes due to we use unique mount source string in tests.
- A7:D7 marked `NOTNEEDED` because we don't set fsGroup on block devices in local plugin. (TODO: Should we set fsGroup on block device?)
- A8:D8 marked `NOTTESTED` because I didn't test it, I leave it to `pull-kubernetes-e2e-gce`. I think it should be same as `blockfs`.

[GCE] Add new formats to resource parser and self link creator
**What this PR does / why we need it**:
- Expands the set of parse-able strings for resource IDs, while also simplifying the code. Note that these are acceptable values for some fields in GCP API.
- global/networks/my-network
- regions/us-central1/subnetworks/my-sub
- zones/us-central1-a/instances/my-hacker-instance
- Fixes the SelfLink function to return links for regions and zones:
- https://www.googleapis.com/compute/v1/projects/proj4/regions/us-central1
- Generates helper functions to create a ResourceID for each resource
- Generates a unit test that ensures all links can be generated and all generated links can be parsed.
- Fixes an ILB test which creates a malformed URL.

remove rootscopedkinds from groupmeta
builds on https://github.com/kubernetes/kubernetes/pull/63206
Since, a RESTMapping can only be determined based on a connection to a server, the only thing that needs to know the namespaced-ness of a resource is the code doing the registration. Everything else is derived from that source of truth. This removes the other dangling references and collapses down onto the existing namespaced-ness methods in the strategies backing the stores.
