Delete federation namespace after the test completes
The code was commented because of a bug in namespace deletion which is now fixed.
Note that this deletes the namespace in federation control plane. We still need to delete the namespace from each cluster (cascading deletion)

Use rsync to probe for rsync ready
We were using netcat to try and figure out when the rsync container is ready. Now we instead use rsync itself. I suspect that there was a race condition with some versions of Docker where it would accept connections and then close them during container start.
This fixes#34214 (I think)

Fix nil pointer issue when getting metrics from volume mounter
Currently it is possible that the mounter object stored in Mounted
Volume data structure in the actual state of kubelet volume manager is
nil if this information is recovered from state sync process. This will
cause nil pointer issue when calculating stats in volume_stat_calculator.
A quick fix is to not return the volume if its mounter is nil. A more
complete fix is to also recover mounter object when reconstructing the
volume data structure which will be addressed in PR #33616

Fix wait.JitterUntil
https://github.com/kubernetes/kubernetes/pull/29743 changed a util method to cause process exits if a handler function panics.
Utility methods should not make process exit decisions. If a process (like the controller manager) wants to exit on panic, appending a panic handler or setting `ReallyCrash = true` is the right way to do that (discussed [here](https://github.com/kubernetes/kubernetes/pull/29743#r75509074)).
This restores the documented behavior of wait.JitterUntil
This patch provides a more relevant error message when a client
configuration option is passed with an invalid or non-existent value.
`$ kubectl get pods --cluster="non-existent"`
```
error: No configuration file found, please login or point to an existing
file
```
`$ kubectl get pods --cluster="non-existent"`
```
error: cluster "non-existent" does not exist
```

kubelet: eviction: avoid duplicate action on stale stats
Currently, the eviction code can be overly aggressive when synchronize() is called two (or more) times before a particular stat has been recollected by cadvisor. The eviction manager will take additional action based on information for which it has already taken actions.
This PR provides a method for the eviction manager to track the timestamp of the last obversation and not take action if the stat has not been updated since the last time synchronize() was run.

Use etcd3.0.10 in integration tests
Also, start testing etcd2->etcd3 migration as part of test-update-storage-object test.
[We are already using etcd 3.0.10 in unit tests. And we are still testing the current binary as part of all e2e tests, which I think is enough. I think we can start using 3.0.10 in integrations tests now.

Some of the main changes:
- add dryrun to annotate (can push this in a different PR if requested)
- use Complete(), Validate() and RunX()
- don't place dynamic variables in the options (only user options and args)
- call the NewBuilder() in the Run function.
You can now do diff between these files and they are as identical as possible.

The implicit registration of Prometheus metrics for workqueue has been removed, and a plug-able interface was added. If you were using workqueue in your own binaries and want these metrics, add the following to your imports in the main package: "k8s.io/pkg/util/workqueue/prometheus".

Speed up dockerized builds
This PR speeds up dockerized builds. First, we make sure that we are as incremental as possible. The bigger change is that now we use rsync to move sources into the container and get data back out.
To do yet:
* [x] Add a random password to rsync. This is 128bit MD4, but it is better than nothing.
* [x] Lock down rsync to only come from the host.
* [x] Deal with remote docker engines -- this should be necessary for docker-machine on the mac.
* [x] Allow users to specify the port for the rsync daemon. Perhaps randomize this or let docker pick an ephemeral port and detect the port?
* [x] Copy back generated files so that users can check them in. This is done for `zz_generated.*` files generated by `make generated_files`
* [x] This should include generated proto files so that we can remove the hack-o-rama that is `hack/hack/update-*-dockerized.sh`
* [x] Start "versioning" the build container and the data container so that the CI system doesn't have to be manually kicked.
* [x] Get some benchmarks to qualify how much faster.
This replaces #28518 and is related to #30600.

The serial test result will be shown on test-grid.
The benchmark test result will be shown [node-perf-dash](http://node-perf-dash.k8s.io/#/builds)
This PR also changes the cri validation test to use the same gci image with node e2e instead of the canary image. The docker version is still 1.11.2.
