Add pending pod check in cluster autoscaler e2e tests
The tests should wait until all pods are running before declaring a success and resizing the mig.

volume integration: wait for PVs before creating PVCs
The test should wait until all volumes are processed by volume controller (i.e. in the controller cache) before creating a PVC.
Without that, the "best" matching PV could not be in the cache and controller might bind the PVC to suboptiomal one.
This fixes integration test flake "Bind mismatch! Expected pvc-2 capacity 50000000000 but got pvc-2 capacity 52000000000".
Fixes#27179 (together with #26894)

Fix integration pv flakes
There are two fixes in this PR:
- run tests in separarate functions and use objects with different names, otherwise events from the beginning of the function are caught later when we watch for events of a different PV/PVC
- don't set PV.Spec.ClaimRef.UID of pre-bound PVs. PVs with UID set are considered as bound and they are deleted/recycled when appropriate PVC does not exists yet.
Fixes#26730 and probably also ~~#26894~~ #26256

e2e: actually check error when we fail to GET the scheduled pod
and GET the pod before we try to gracefully delete it.

Considering all nodes for the scheduler cache to allow lookups
Fixes the actual issue that led me to create https://github.com/kubernetes/kubernetes/issues/22554
Currently the nodes in the cache provided to the predicates excludes the unschedulable nodes using field level filtering for the watch results. This results in the above issue as the `ServiceAffinity` predicate uses the cached node list to look up the node metadata for a peer pod (another pod belonging to the same service). Since this peer pod could be currently hosted on a node that is currently unschedulable, the lookup could potentially fail, resulting in the pod failing to be scheduled.
As part of the fix, we are now including all nodes in the watch results and excluding the unschedulable nodes using `NodeCondition`

Port the downward api test to the node e2e suite
Also extend the framework to allow a custom client config loading function, so
that the node e2e suite can reuse the same framework across tests.
This fixes#26609

Add e2e test for node problem detector
Based on https://github.com/kubernetes/node-problem-detector/pull/12.
This PR added e2e test for node problem detector. It starts a node problem detector with test configuration, and test its functionality.
Question:
* Should this be a node e2e test or e2e test?
* Should we mark this as Serial? The test should not affect other tests, but it will add a `TestConditon` in node conditions and remove in cleanup.

Listing pods only once when getting pods for RS in deployment
Fixes#26834
1. Avoid ranging over RSes and then `List` pods of each RS. Instead, `List` pods of the deployment once, and then filter pods of each RS.
2. Avoid using clientset to `List` pods in deployment controller. Use podStore instead. (TODO in some functions because the unit tests don't have podStore.)

support for mounting local-ssds on GCI
This change adds support for mounting local ssds on GCI.
It updates the previous container-vm behavior as well to
match that for GCI nodes by mounting the local-ssds under
the same path (/mnt/disks/ssdN).

Enable WatchCache in test/integration/ tests
We already run cmd/integration/ with watch cache on. We should also run tests in test/integration/ with watch cache on.
