8a908e0c0b remove import doc comments 
The "// import <path>" comment has been superseded by Go modules.
We don't have to remove them, but doing so has some advantages:

- They are used inconsistently, which is confusing.
- We can then also remove the (currently broken) hack/update-vanity-imports.sh.
- Last but not least, it would be a first step towards avoiding the k8s.io domain.

This commit was generated with
   sed -i -e 's;^package \(.*\) // import.*;package \1;' $(git grep -l '^package.*// import' | grep -v 'vendor/')

Everything was included, except for
   package labels // import k8s.io/kubernetes/pkg/util/labels
because that package is marked as "read-only".

b584b87a94 kube-controller-manager: readjust log verbosity 
- Increase the global level for broadcaster's logging to 3 so that users can ignore event messages by lowering the logging level. It reduces information noise.
- Making sure the context is properly injected into the broadcaster, this will allow the -v flag value to be used also in that broadcaster, rather than the above global value.
- test: use cancellation from ktesting
- golangci-hints: checked error return value

99151c39b7 kube-controller-manager: convert to structured logging 
Most of the individual controllers were already converted earlier. Some log
calls were missed or added and then not updated during a rebase. Some of those
get updated here to fill those gaps.

Adding of the name to the logger used by each controller gets
consolidated in this commit. By using the name under which the
controller is registered we ensure that the names in the log
are consistent.

3c88de52c8 controller/nodelifecycle: Make monitorNodeHealth process nodes concurrently 
Marking the pods not ready on a node requires looping over them and
updating each pod's status one at a time. This is performed serially,
and can take a while if we're processing each node serially as well.

Since the time is spent waiting on io, there's an opportunity to go
faster by processing multiple nodes concurrently. This change modifies
the loop to process nodes in parallel, using the same number of workers
as doNodeProcessingPassWorker.

This change also introduces histogram metrics to better observe
monitorNodeHealth.

de25c5fdcf NodeLifecycleController: Remove race condition 
Patch request does not support RV by default, we need to include them explicitly and patching lists actually overwrites whole field. It means that there is a race condition, in which we can overwrite changes to taints that happened between GET and PATCH requests.
