[garbage collector] add e2e test
This PR also includes some changes to plumb controller-manager's `--enable_garbage_collector` from the environment variable.
The e2e test will not be run by the core suite because it's marked `[Feature:GarbageCollector]`.
The corresponding jenkins job configuration PR is https://github.com/kubernetes/test-infra/pull/132.

Return server's representation of pod from framework pod creation functions
Since PodInterface.Create returns the server's representation of the pod, which may differ from the api.Pod object passed to Create, we do the same from the framework's pod creation functions. This is useful if e.g. you create pods using Pod.GenerateName rather than Pod.Name, and you still want to refer to pods by name later on (e.g. for deletion).

e2e: increase timeout when waiting for deployment pods to be deleted
Use the same timeout as the one used for waiting for the deployment
reaper to complete.

Remove duplicated nginx image. Use nginx-slim instead
This PR removes the image `gcr.io/google_containers/nginx:1.7.9` and uses `gcr.io/google_containers/nginx-slim:0.7`.
Besides removing the duplication `1.7.9` is 16 months old.

Fix federation e2e tests by correctly managing cluster clients
1. The main fix: Correct overall BeforeEach() to create a new set of cluster clients, rather than just append to the set created by all previous tests. This was screwing up a lot of stuff in difficult to diagnose ways.
2. Add lots of debug logging.
3. Be better about cleaning up after each test.

SUCCESS! -- 6 Passed | 0 Failed :-)

e2e: Allow skipping tests for specific runtimes, skip a few tests under rkt
The main benefit of this is that it gives a developer more useful output (more signal to noise) for things that are known broken on that runtime.

I'll run this PR through our jenkins and make sure things look happy and compare to the e2e results for this PR.

[Refactor] QOS to have QOS Class type for QoS classes
This PR adds a QOSClass type and initializes QOSclass constants for the three QoS classes.
It would be good to use this in all future QOS related features.
This would be good to have for the (Pod level cgroups isolation proposal)[https://github.com/kubernetes/kubernetes/pull/26751] that i am working on aswell.

e2e.framework.util.StartPods: panic if the number or replicas is zero
The number of pods to start must be non-zero.
Otherwise the function waits for pods forever if ``waitForRunning`` is true.
It the number of replicas is zero, panic so the mistake is heard all over the e2e realm.
Update all callers of StartPods to test for non-zero number of replicas.

e2e: Delete old code
These tests were added commented out over a year ago. Now they don't compile. The port forward test has a whole file devoted to replacing it (`e2e/portforward.go`) and while the exec test doesn't have a perfect replacement, it has several tests that cover for it (exec over a websocket, an e2e_node test, all the kubectl execs). If we want that test, it would be better to write it fresh anyways.

Use gcloud for default node pool and api for other in cluster autoscaler e2e test
cc: @piosz @jszczepkowski @fgrzadkowski
Currently there is a problem with gcloud when non-default pool is used for cluster update. So we temporarily switch to the old ca-enable method for non-default pools until it is fixed.

A few changes to federated-service e2e test.
Most of the changes that get the test to pass have been made already or
elsewhere. Here we restructure a bit fixing a nesting problem, extend the
timeouts, and start creating distinct backend pods that I'll delete in the
non-local test (coming shortly).
Also some extra debugging info in the DNS code. I made some upstream
changes to skydns in https://github.com/skynetservices/skydns/pull/283

increase addon check interval
Do static pods have a crash loop back off? If so, this test would be much faster if we restarted the kubelet to clear that.

Fix 7 broken example e2e tests
Fixes#27325, Fixes#27727
7 broken example e2e tests:
- [x] Spark
* `namespace` is specified in example yaml files which conflict with e2e test namespaces, fixed by removing the namespace in yaml (the yaml files of [spark example](https://github.com/kubernetes/kubernetes/tree/master/examples/spark) doesn't need the namespace specified since it's specified in its context) -- cc @k82 who added namespace to Spark example in #23807
* wait for pods to exist before determining if it's running
- [x] Hazelcast
* wait for pods to exist before determining if it's running
- [x] Redis
* image `kubernetes/redis:v2` is not found, changed to `kubernetes/redis:v1` instead
* wait for pods to exist before determining if it's running
- [x] Celery-RabbitMQ
* remove 1 redundant call to `forEachPod`
* wait for pods to exist before determining if it's running
- [x] Cassandra
* fix `kubectl exec` on incorrect pod name
* fix getting endpoint ip addresses before creating pods
* wait for pods to exist before determining if it's running
- [x] Storm
* wait for pods to exist before determining if it's running
- [x] RethinkDB
