Increase goroutinemap unit test timeouts.
50ms is flaky in Jenkins. This makes the test to take at least 0.5s to check that things that should block and wait for something really do block and wait (was 100ms before).

Refactor storePodsNamespacer.List()
This fixes a bug in the previous version where, when we fell back on a
brute force approach, we were still returning an error.
It also clarifies the flow control into 3 distinct cases. The cases
don't share variables any more, which makes mistakes like the one
mentioned above harder.

use kubectl-with-retry on pause & resume
attempts to fix https://github.com/kubernetes/kubernetes/issues/25645 by using `kubectl-with-retry` on `rollout {pause,resume}` (`resume` is for safe measures) instead of `kubectl` directly, as is done with other `rollout {pause,resume}` tests in this same script.

Flake 21484: retrieve pod log during e2e error
Print the pod log when an error occurs in

e2e test. This will help to understand flake https://github.com/kubernetes/kubernetes/issues/21484 better.

volume controller: use better operation names
Using volume/claim.UID in the operation name is not really useful, as UIDs are not logged by rest of the controller. On the other hand, volume.Name and claim.Namespace/Name is logged pretty often and it would help to log these also in operation name. Still, I'd prefer to have the operation name really unique to be protected from users deleting a volume and quickly creating another one with the same name, so UID is still part of the operation name.
This has been already proven to be very useful in controller debugging.

Use docker containerInfo.LogPath and not manually constructed path
## Pull Request Guidelines
Since the containerInfo has the LogPath in it, let's use that and
not manually construct the path ourselves. This also makes the code
less prone to breaking if docker change this path.
Fixes#23695
Refactor storePodsNamespacer.List() and
storeReplicationContollersNamespacer.List(). They are the same
function, just with different signatures.
This fixes a bug where, when we fell back on a brute force approach, we
were still returning an error.
Also change to explicit return without named return values.

Ensure that init containers are preserved during pruning
Pods with multiple init containers were getting the wrong containers
pruned. Fix an error message and add a test.

Add some extra checking in the tests to prevent flakes.
Attempts to fix https://github.com/kubernetes/kubernetes/issues/25967
The hypothesis is that somehow waitTest() catches an idle that occurs before all changes have been applied. This will block until the expected number of changes have arrived.

use monotonic now in TestDelNode
Fixes https://github.com/kubernetes/kubernetes/issues/24971.
Briefly, the rate_limited_queue uses a `container/heap` to store values, and use this data structure to ensure we can always fetch the value with the minimum `processAt`. However, in some extreme condition, the continuous call to `time.Now()` would get the same value, which causes some unpredictable order in the queue, this fix uses a monotonic `now()` to avoid that.
@smarterclayton please take a look.
This is needed for the /etc/hosts mount and the downward API to work.
Furthermore, this is required for the reported `PodStatus` to be
correct.
The `Status` bit mostly worked prior to #25062, and this restores that
functionality in addition to the new functionality.
