[Federation] Deployments unaware of ReadyReplicas
The Deployment controller was not propagating ReadyReplicas to underlying clusters causing these errors:
```
Error syncing cluster controller: Deployment.apps "federation-deployment" is invalid: status.availableReplicas: Invalid value: 5: cannot be greater than readyReplicas
```
This was caught in e2e testing and is a 1.6 regression for support that was added in #37959. Without this fix, users will be unable to scale up their deployments.

Arrange for elasticsearch to shutdown cleanly
Kubernetes initiates "graceful shutdown" by sending SIGTERM to pid 1, which
is exactly what elasticsearch is expecting (good!)
The way the existing startup scripts worked however, this signal arrived at
the shell wrapper, not elasticsearch, and the shell wrapper exited,
killing the container immediately (bad!)
Before this change:
```
1 ? Ss 0:00 /bin/sh -c /run.sh
6 ? S 0:00 /bin/bash /run.sh
13 ? S 0:00 \_ /bin/su -c /elasticsearch/bin/elasticsearch elasticsearch

15 ? Sl 19:18 \_ /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java ... org.elasticsearch.bootstrap.Elasticsearch start
```
After this change:
```

Let GC print specific message for RESTMapping failure
Make the error messages reported in https://github.com/kubernetes/kubernetes/issues/39816 to be more specific, also only print the message once.
I'll also update the garbage collector's doc to clearly state we don't support tpr yet.
We'll wait for the watchable discovery feature (@sttts are you going to work on that?) to land in 1.7, and then enable the garbage collector to handle TPR.

Fix deployment generator after introducing deployments in apps/v1beta1
This PR does two things:
1. Switches all generator to produce versioned objects, to bypass the problem of having an object in multiple versions, which then results in not having stable generator (iow. producing exactly the same object).
2. Introduces new generator for `apps/v1beta1` deployments.

Return nil when deleting non-exist GCE PD
When gce cloud tries to delete a disk, if the disk could not be found
from the zones, the function should return nil error. This modified behavior is also consistent with AWS

Use Prometheus instrumentation conventions
The `System` and `Subsystem` parameters are subject to removal.
(x-ref: https://github.com/prometheus/client_golang/issues/240)
All metrics should use base units, which is seconds in the duration
case.
Counters should always end in `_total` and metrics should avoid
referring to potential label dimensions. Those should rather be
mentioned in the documentation string.
@kubernetes/sig-instrumentation
Reference docs:
https://prometheus.io/docs/practices/instrumentation/https://prometheus.io/docs/practices/naming/
**Release note**:
```
Breaking change: Renamed REST client Prometheus metrics to follow the instrumentation conventions ("request_latency_microseconds" -> "rest_client_request_latency_seconds", "request_status_codes" -> "rest_client_requests_total"). Please update your alerting pipeline if you rely on them.

e2e test: Log container output on TestContainerOutput error
When a pod started with TestContainerOutput or TestContainerOutputRegexp
fails from unknown reason, we should log all output of all its containers
so we can analyze what went wrong.
This would help us to see what wrong in https://github.com/kubernetes/kubernetes/issues/40811 - a container is running there for 3 minutes and dies and we want to see what it did for these 3 minutes.

Change the junit file name format to `junit_image-name_id.xml`,
With this, the junit file name will be `junit_image-name_id.xml:
```
junit_containervm_id.xml
junit_coreos-alpha_id.xml
junit_gci_id.xml
junit_ubuntu-docker10_id.xml
junit_ubuntu-docker12_id.xml
```
The test infra team will use the `image-name` inside the junit file name and replace the original `[1] [2] [3] ..` with the actual image name.
This will make it a little bit easier for debugging.
