Enhance label and taint documentation in kubectl
**What this PR does / why we need it**:
This adds some language around how taint and label keys can have a domain + '/' in front of them. From the current documentation, it would seem like these are not allowed even though [well known labels](https://kubernetes.io/docs/reference/labels-annotations-taints/) have them.
Also, it seemed unclear (to me) that both the label's key and value can be 63 characters long. I wanted to clarify this.

dockershim: remove corrupt checkpoints immediately upon detection
Fixes https://github.com/kubernetes/kubernetes/issues/55620
The current checkpoint abstraction leaks the handling of corrupt checkpoints to the user.
If the user does a `GetCheckpoint()` and the checkpoint is corrupt, the corrupt checkpoint is returned to the user (why??) with an error indicating the corruption. It is then up to the user to detect the corruption via the error msg and call `RemoveCheckpoint()` to remove the corrupted checkpoint.
The checkpoint abstraction should not expose corruption to the user. If it is corrupt, it is as good as not found to the user. The checkpoint code should handle cleanup of corrupt entries and report "not found" to the user.

Fix an unreachable kubectl explain field lookup test
In error case, the condition `gotErr != test.err && gotPath !=
test.expectedPath` never fulfill because in this case both gotPath and
test.expectedPath are always an empty string. So the err “err: `field "what?"
does not exist`” doesn’t get tasted. For example, if you change the value of
`err:` to anything, the test still will pass. Also, since gotPath is empty
string in case of err, in the output error we probably don’t want to display
path.
