At present, there is no way for a hint provider to return distinct hints
for different resource types via a call to GetTopologyHints(). This
means that hint providers that govern multiple resource types (e.g. the
devicemanager) must do some sort of "pre-merge" on the hints it
generates for each resource type before passing them back to the
TopologyManager.
This patch changes the GetTopologyHints() interface to allow a hint
provider to pass back raw hints for each resource type, and allow the
TopologyManager to merge them using a single unified strategy.
This change also allows the TopologyManager to recognize which
resource type a set of hints originated from, should this information
become useful in the future.
We tried to separate logger functionality as subpackage of e2e test
framework, but we've recognized that should be core functionality
and we should keep it as core of e2e test framework after facing
circular dependency issues.
So this adds log.go back to core of e2e test framework. In addition,
this makes volume sub package use the core logger as a sample.
Also remove FS VolMode disruptive tests because they are already covered
through the subpath disruptive test cases.

Etcd v3.3.0 added the --listen-metrics-urls flag which allows specifying
addition URLs to the already present /health and /metrics endpoints.
While /health and /metrics are enabled for URLS defined with
--listen-client-urls (v3+ ?) they do require HTTPS.
Replace the present etcdctl based liveness probe with a standard HTTP
GET v1.Probe that connects to http://127.0.0.1:2381/health.
These endpoints are not reachable from the outside and only available
for localhost connections.
ConfirmStatefulPodCount() was used at e2e statefulset test only,
and that added dependency on another sub framework to statefulset
sub framework. This moves ConfirmStatefulPodCount() to the e2e test
for clean dependency.
Includes the changes from #80922 (that were reverted), and updates the test to appropriately add intolerable taints to all nodes except the target node
DesiredStateOfWorldPopulator should skip a volume that is not used in any
pod. "Used" means either mounted (via volumeMounts) or used as raw block
device (via volumeDevices).
Especially when block feature is disabled, a block volume must not get into
DesiredStateOfWorld, because it would be formatted and mounted there.
