Instead of N pointers, we were returning N null pointers, followed by the real
thing. It's not clear why we didn't trip on this until now, maybe there is a
new server-side check for empty subnetID strings.

Limit concurrent route creations
Ref #26119
This is supposed to improve 2 things:
- retry creating route in routecontroller in case of failure
- limit number of concurrent CreateRoute calls in flight.
We need something like that, because we have a limit of concurrent in-flight CreateRoute requests in GCE.

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.

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.

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.
