hack: specify --advertise-address in hack/local-up-cluster.sh
This fixes the bug where the script fails to launch an apiserver on a
machine without active networking (issue #24272).

Fix spacing in usage_from_stdin and info_from_stdin (issue #24186).
If "a" is a bash array, then the syntax to append the contents of $line as a
new element to the array is a+=("$line"), not messages+=$line
Using the former syntax just seems to append to the first element, creating a
long string and thus losing newline information.
Fixing this allows us to drop some empty lines from invocations of
usage_from_stdin.

Asynchronous bindings
This increases scheduler throughput with "trivial algorithm" (choose random node) by at least 5x.
Such optimization is necessary if we want to significantly improve scheduling throughput.

```console

Make kubectl edit not convert GV on edits
Previously, kubectl edit was using a decoder to load in edits that
converted to the internal version. It would then re-encode this
decoded value to produce a patch. However, if you were editing
in the object in a GroupVersion that was not the internal version,
this would cause the kubectl edit command to attempt to produce
a patch which changed the GroupVersion, which would fail.
Now, we use a plain deserializer instead, so no conversion or
defaulting occurs when loading in the edited file.

Rename "gcloud-update" jobs to "daily-maintenace" and add Docker cleanup
I'm guessing Jenkins Job Builder won't delete the old job, and we'll need to do that manually?

phase 2 of cassandra example overhaul
Here's the next iteration in overhauling this example, towards https://github.com/kubernetes/kubernetes/issues/20961. This removes the pod adoption part, but doesn't (yet) otherwise change any of the resources used.
It also includes some README cleanup, and removes some explicit specification of labels in the rc yaml.
This PR doesn't yet add any commentary on how we're using the seed provider (re: https://github.com/kubernetes/kubernetes/issues/20961#issuecomment-190405959 etc.). Maybe we should add that.
Also: LMK if this PR should include any changes to the links out to the docs.

Restart job 5m after the previous failure.
If a job flakes at the beginning of it scripts, it will likely sit around doing nothing for 30m blocking the merge queue. Decreasing this to 5m.

rkt: Use rkt pod's uuid as the systemd service file's name.
Previously, the service file's name is 'k8s_${POD_UID}.service',
which means we need to `systemctl daemon-reload` if the we replace
the content of the service file (e.g. pod is restarted).
However this makes the journal in the previous pod get disconnected.
This PR solves the issue by using the unique rkt uuid as the service
file's name. After the change, the service file's name will be:
'k8s_${rkt_uuid}.service'.

don't ship kube-registry-proxy and pause images in tars.
pause is built into containervm. if it's not on the machine we should just pull
it. nobody that I'm aware of uses kube-registry-proxy and it makes build/deployment
more complicated and slower.

Allow lazy binding in credential providers; don't use it in AWS yet
This is step one for cross-region ECR support and has no visible effects yet.
I'm not crazy about the name LazyProvide. Perhaps the interface method could
remain like that and the package method of the same name could become
LateBind(). I still don't understand why the credential provider has a
DockerConfigEntry that has the same fields but is distinct from
docker.AuthConfiguration. I had to write a converter now that we do that in
more than one place.
In step two, I'll add another intermediate, lazy provider for each AWS region,
whose empty LazyAuthConfiguration will have a refresh time of months or years.
Behind the scenes, it'll use an actual ecrProvider with the usual ~12 hour
credentials, that will get created (and later refreshed) only when kubelet is
attempting to pull an image. If we simply turned ecrProvider directly into a
lazy provider, we would bypass all the caching and get new credentials for
each image pulled.
