After a CRD or an APIService was deleted, the corresponding group was
never unregistered. It caused a stale entry to remain in the root path
and could potentially lead to memory leak as the groupDiscoveryHandler
was never released and the handledGroups was never cleaned up.
The commit implements the cleanup. It tracks each group's usage and
unregister the a group when there is no version for this group.

TestSampleAPIServer tried to validate APIService deletion, but it used
an unmatched selector to delete and list APIServices, which essentially
validated nothing.

Some test cases can make nodes not ready and use DeferCleanup to bring
nodes back online. Checking if all nodes are online would fail
in such cases as AfterEach runs before DeferCleanup.
Scheduling nodes readines check to DeferCleanup should solve this
issue as nodes would be brought back to a `Ready` state before the
check.
Add retry mechanism to handle cases where after kubelet restarts, the device
plugin unix socket(s) were created but not ready to serve yet.

Add kubeletSocket file to fsnotify instead of polling and waiting for deletion
of device plugin unix socket as a way of detecting kubelet restart. We need to
ensure that the device plugin re-registers itself after kubelet restart depending
on the configured registration mode (auto-registration or controller registration).

If the user specifies the intent to control registration process, we rely on
registration triggers (deletion of control file) to prompt registration.
This behvaiour is expected to be consistent across kubelet restarts and therefore
across the watch calls where we watch for changes to the unix socket so we make
this part of Stub object instead of a parameter.
