kubelet/envvars: Adding brackets to IPv6 addresses
Signed-off-by: André Martins <aanm90@gmail.com>
**What this PR does / why we need it**: This adds IPv6 brackets on environments variables pods
**Special notes for your reviewer**:
Since the IP is a string I think the fastest way to detect if it's an IPv6 was to check for the presence of `:` in it. Let me know what you think.

- pkg/kubelet/volumemanager/populator/desired_state_of_world_populator.go

[Bug Fix] Return quantity freed even when an error exists
bug was added by #44986. If we get an error from deleteImages, we try and use the bytes freed in a calculation.
That PR changed the behavior from evicting a pod upon error, to panicking because of the nil pointer.
This should fix inode eviction tests

Tighten validation of mirror pod annotations
Tightens validation for pods with a mirror pod annotation:
1. spec.nodeName must be set
2. makes the mirror pod annotation immutable
3. starts validating pod-specific annotations during pod status update
None of these changes affect usage of the mirror pod annotation by kubelets, which only set it on pod creation (verified this is true back to 1.5.x)
the second commit updates the pod validation tests to look for specific error messages (best reviewed ignoring whitespace changes)
This is the validation portion of https://github.com/kubernetes/community/blob/master/contributors/design-proposals/kubelet-authorizer.md and https://github.com/kubernetes/features/issues/279
```release-note
Mirror pods must now indicate the nodeName they are bound to on creation. The mirror pod annotation is now treated as immutable and cannot be added to an existing pod, removed from a pod, or modified.

Allow certificate manager to be initialized with client.
Add test coverage to the certificate manager covering the initialization
scenario where it is initialized with no Certificate Request Signing
client, then the client is added later. This matches how it will be used
when the Certificate Request Signing client is also the consumer of the
certificate manager.

Reorganize kubelet tree so apis can be independently versioned
@yujuhong @lavalamp @thockin @bgrant0607
This is an example of how we might reorganize `pkg/kubelet` so the apis it exposes can be independently versioned. This would also provide a logical place to put the `KubeletConfiguration` type, which currently lives in `pkg/apis/componentconfig`; it could live in e.g. `pkg/kubelet/apis/config` instead.
Take a look when you have a chance and let me know what you think. The most significant change in this PR is reorganizing `pkg/kubelet/api` to `pkg/kubelet/apis`, the rest is pretty much updating import paths and `BUILD` files.

Don't attempt to make and chmod subPath if it already exists
fixes https://github.com/kubernetes/kubernetes/issues/45613https://github.com/kubernetes/kubernetes/pull/43775 fixed one bug and introduced another... I overlooked that subPaths can be files, in which case MkDirAll will simply fail and the pod will not able to start.
Regardless of whether it is a directory or a file, there is no need to introduce the MkdirAll->Chmod procedure if it exists, because if it exists, it should already have the correct permissions.
This needs to be cherry-picked into 1.6.

Fix pods failing to start if they specify a file as a volume subPath to mount

rkt: Improve the Garbage Collection
**What this PR does / why we need it**:
This PR improve the garbage collection of files written inside the `/var/lib/kubelet/pods/<pod: id>`
It removes the` finished-<pod: id>` file touched during the `ExecStopPost` of the systemd unit.
It also removes the `/dev/termination-log` file mounted into containers .
The termination-log is used to produce a message from the container and collected by the kubelet when the Pod stops.
Especially for the termination-log, removing theses files will free the associated space used on the filesystem.

Fix AssertCalls usage for kubelet fake runtimes unit tests
Despite its name, AssertCalls() does not assert anything. It returns an error that should be checked. This was causing false negatives for a handful of unit tests, which are also fixed here.
Tests for the image manager needed to be rearranged in order to accommodate a potentially different sequence of calls each tick because the image puller changes behavior based on prior errors.
