Restore "Setting endpoints" log message
**What this PR does / why we need it**:
The "Setting endpoints" message from kube-proxy at high verbosity was
lost as part of a larger simplification in kubernetes/kubernetes#42747.
This change brings it back, simply outputting the just-constructed
addresses list.
I need this message to monitor delays in propagating endpoints changes across nodes.

Proxy healthchecks overhaul
The first commit is #44051
These three commits are tightly coupled, but should be reviewed one-by-one. The first adds tests for healthchecks, and found a bug. The second basically rewrites the healthcheck pkg to be much simpler and less flexible (since we weren't using the flexibility). The third tweaks how healthchecks are handled in endpoints-path to be more like they are in services-path.
@MrHohn because I know you were in here for source-IP GA work.

Update deployment retries to a saner count
It seems that the current retries sum up to no more than 0.2s so some transient errors may drop deployments out of the queue.

Wait for clean old RSs statuses in the middle of Recreate rollouts
After https://github.com/kubernetes/kubernetes/pull/43508 got merged, we started returning ReplicaSets with no pods but with stale statuses back to the rollout functions. As a consequence, one of our e2e tests that checks if a Recreate Deployment runs pods from different versions, started flakying because the Deployment status may be incorrect. This change simply waits for the statuses to get cleaned up before proceeding with scaling up the new RS.
Fixes https://github.com/kubernetes/kubernetes/issues/43864

kube-proxy: filter INPUT as well as OUTPUT
We need to apply filter rules on the way in (nodeports) and out (cluster
IPs). Testing here is insufficient to have caught this - will come back
for that.

```release-note
Fix bug with service nodeports that have no backends not being rejected, when they should be. This is not a regression vs v1.5 - it's a fix that didn't quite fix hard enough.

Updated AddOrUpdateTolerationInPod to return bool only, as there's no case to generate error (the error was used for annotation, it'll not return error after moving to field); and also update admission & daemonset accordingly.

The existing healthcheck lib was pretty complicated and was hiding some
bugs (like the count always being 1), This is a reboot of the interface
and implementation to be significantly simpler and better tested.

Use shared informers for proxy endpoints and service configs
Use shared informers instead of creating local controllers/reflectors
for the proxy's endpoints and service configs. This allows downstream
integrators to pass in preexisting shared informers to save on memory &
cpu usage.
This also enables the cache mutation detector for kube-proxy for those
presubmit jobs that already turn it on.

Adding test cases for HC updates found a bug with an update that
simultaneously removes one port and adds another. Map iteration is
randomized, so sometimes no HC would be created.

Change an Errorf to a Fatalf to prevent a panic.
In #37982 we see that if this error is hit then we will panic on the next line. Lets use `Fatalf` where appropriate :)
This does *not* fix the flake, since that's caused by the test assuming that a particular port is free.

Clearer ImageGC failure errors. Fewer events.

Remove 'beta' from default storage class annotation (storage/util)
**What this PR does / why we need it**:
This is a follow up to: #42991 where I believe this file was overlooked.
It removes `beta` from the default storageclass annotation.
Without this fix you are not able to specify a default storage class like this:
```yaml
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: standard
annotations:
storageclass.kubernetes.io/is-default-class: "true"
provisioner: kubernetes.io/aws-ebs
parameters:
type: gp2
```
because the annotation is ignored in: https://github.com/kubernetes/kubernetes/blob/master/plugin/pkg/admission/storageclass/default/admission.go#L129

This signature is more consistent with OnEndpointsUpdate and removes a
