This commit updates `kubectl describe` to display the new HPA
status conditions. This should make it easier for users to discern
the current state of the HPA.
This commit causes the HPA controller to set a variety of status
conditions using the new `Status.Conditions` field of
autoscaling/v2alpha1. These provide insight into the current state
of the HPA, and generally correspond to similar events being emitted.
This commit adds the new API status conditions to the API types.
The field exists as a field in autoscaling/v2alpha1, and is
round-tripped through an annotation in autoscaling/v1.

Add iptables lock-file mount to kube-proxy manifest
**What this PR does / why we need it**: kube-proxy is broken in make bazel-release. The new iptables binary uses a lockfile in "/run", but the directory doesn't exist. This causes iptables-restore to fail. We need to share the same lock-file amongst all containers, so mount the host /run dir.
This is similar to #46132 but expediency matters, since builds are broken.

OpenAPI aggregation for kube-aggregator
This PR implements OpenAPI aggregation layer for kube-aggregator. On each API registration, it tries to download swagger.spec of the user api server. On failure it will try again next time (either on another add or get /swagger.* on aggregator server) up to five times. To merge specs, it first remove all unrelated paths from the downloaded spec (anything other than group/version of the API service) and then remove all unused definitions. Adding paths are straightforward as they won't have any conflicts, but definitions will most probably have conflicts. To resolve that, we would reused any definition that is not changed (documentation changes are fine) and rename the definition otherwise.
To use this PR, kube aggregator should have nonResourceURLs (for get verb) to user apiserver.

Support OpenAPI spec aggregation for kube-aggregator

Add SuccessfulMountVolume message to the events of pod
**What this PR does / why we need it:**
When creating a pod with volume, the volume mount may failed at first, but eventually succeed after retry several times. kubectl describe pod can only see the failed messages, so i think it will be better to add the SuccessfulMountVolume message to the pod events too.

Fixes#42867
This is part of the namespace deletion big hammer. `kubefed join` not
just creates federation-system namespace, but also cluster role and
cluster role bindings in the joining clusters. Sometimes unjoin fails
to delete them. So we use a big hammer here to delete them.
This smells like a real problem in kubefed and needs investigation.
This is a short term fix to unblock the submit queue.
This is a big hammer. `kubefed join` creates federation-system namespace
in the joining clusters if they don't already exist. This namespace
usually exists in the host cluster and hence cannot be deleted while
unjoining. So in order to be safe, we don't delete the federation-system
namespace from any federated cluster while unjoining them. This causes
a problem in our test environment if certain resources are left in the
namespace. Therefore we are deleting all federation-system namespace in
all the clusters.
PV is a non-namespaced resource. Running `kubectl delete pv --all`, even
with `--namespace` is going to delete all the PVs in the cluster. This
is a dangerous operation and should not be deleted this way.
Instead we now retrieve the PVs bound to the PVCs in the namespace we
are deleteing and delete only those PVs.
Fixes issue #46380.

Respect PDBs during node upgrades and add test coverage to the ServiceTest upgrade test.
This is still a WIP... needs to be squashed at least, and I don't think it's currently passing until I increase the scale of the RC, but please have a look at the general outline. Thanks!
Fixes#38336

On GCE, node upgrades will now respect PodDisruptionBudgets, if present.
