CRI: Image pullable support in dockershim
For #33189.
The new test `ImageID should be set to the manifest digest (from RepoDigests) when available` introduced in #33014 is failing, because:
1) `docker-pullable://` conversion is not supported in dockershim;
2) `kuberuntime` and `dockershim` is using `ListImages with image name filter` to check whether image presents. However, `ListImages` doesn't support filter with `digest`.
This PR:
1) Change `kuberuntime.IsImagePresent` to use `runtime.ImageStatus` and `dockershim.InspectImage` instead. ***Notice an API change: `ImageStatus` should return `(nil, nil)` for non-existing image.***
2) Add `docker-pullable://` support.
3) Fix `RemoveImage` in dockershim https://github.com/kubernetes/kubernetes/pull/29316.
I've tried myself, the test can pass now.

Ignore mirror pods with RestartPolicy == Never in restart tests
Kubelet does not sync the mirror pods once they have terminated. If, for some
reason, that such mirror pods get deleted once they have terminated (either by
the node controller or by users), kubelet will not attempt to recreate them.
However, when kubelet restarts, it will examine the static pods, sync once,
and create a mirror pod. This has led to unexpected pod counts in disruptive
tests where kubelet gets restarted on purpose (see #34003).
This change disregard such mirror pods when totaling the pods to fix the test
flake until we have time to implement a long-term solution.

Append first address from `--api-advertise-addresses` to `kube-apiserver` flags
**What this PR does / why we need it**:
We have `--api-advertise-addresses` already, but it's only used for SANs in server certificates we generate. Currently setting this flag doesn't affect what address API server advertises, and this PR fixes that. In particular, this has been an issue for VirtualBox users (see #34101).
**Which issue this PR fixes**: fixes#34101
**Release note**:
```release-note
Make `kubeadm` append first address from `--api-advertise-addresses` to `kube-apiserver` flags as `--advertise-address`
```

Checking function integrated with get from chanel in fed tests
Current federation controller tests assume that each actions results in only one etcd action. However, due to various timing issues, this may not necessary the truth and multiple updates can be generated. Thus tests should try to get all available messages from the debug channels instead failing on the first message, which may come from the previous test scenario.
Applied to deployment tests. Other tests will be updated in the following PR(s).

test: move deployment deletion in its own test
@kubernetes/deployment this PR moves the deletion of deployment in its own test (no need to delete deployments in every test since the namespace controller does that for us once the namespace gets deleted after the test finishes)

Avoid unnecessary decoding in etcd3 client
Ref https://github.com/kubernetes/kubernetes/issues/33653
With the "Cacher" layer in Kubernetes, most of the watches processed by "pkg/storage/etcd3/watcher.go" have "filter = Everything()". That said, we generally don't need to decode previous value of the object (which is used only to get the value of filter of it), because we already know it will be true.
This PR is basically fixing this problem.
Should be merged after https://github.com/kubernetes/kubernetes/pull/34246

[WIP] AWS compatibility for federation cluster and e2e
I've been testing this and have reached a point where the e2e tests run, and some test failures are popping up which are not overtly related to AWS specific things.

If you delete a source file, we want to reflect that in the build container. We
only use --delete going that one way as we don't want to accidentally delete

filter informer actions when inspecting controller unit test reactions
fixes https://github.com/kubernetes/kubernetes/issues/34547
There's a race where the informer tries to start list/watching and that can happen faster than the reaction test. This simply filters it.
