[federation][e2e] Increase timeout waiting for service shard to appear

Most of recent federation service tests are failing with timeouts. although some times they do pass, giving kind of flaky nature. So increasing the timeout waiting for service shard to appear in federated cluster from 1 min to 5 mins.

[Federation] Use and return created replicaset instead of the passed object.

Passed replicaset object doesn't contain object name, but has a prefix set in `GenerateName`. However, we need to operate on the object name later to uniquely identified the created object. So we need the created object with the name set by the API server.

Deployment: Fully Respect ControllerRef

**What this PR does / why we need it**:

This is part of the completion of the [ControllerRef](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/controller-ref.md) proposal. It brings Deployment into full compliance with ControllerRef. See the individual commit messages for details.

**Which issue this PR fixes**:

This ensures that Deployment does not fight with other controllers over control of Pods and ReplicaSets.

Ref: https://github.com/kubernetes/kubernetes/issues/24433

**Special notes for your reviewer**:

**Release note**:

```release-note
Deployment now fully respects ControllerRef to avoid fighting over Pods and ReplicaSets. At the time of upgrade, **you must not have Deployments with selectors that overlap**, or else [ownership of ReplicaSets may change](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/controller-ref.md#upgrading).

New e2e node test suite with memcg turned on

The flag --experimental-kernal-memcg-notification was initially added to allow disabling an eviction feature which used memcg notifications to make memory evictions more reactive.
As documented in #37853, memcg notifications increased the likelihood of encountering soft lockups, especially on CVM.

This feature would valuable to turn on, at least for GCI, since soft lockup issues were less prevalent on GCI and appeared (at the time) to be unrelated to memcg notifications.

In the interest of caution, I would like to monitor serial tests on GCI with --experimental-kernal-memcg-notification=true.

[Fix Flaky Tests] E2e Node Flaky test suite runs serially

The [e2e Node Flaky Test Suite](https://k8s-testgrid.appspot.com/google-node#kubelet-flaky-gce-e2e&width=20) has been failing with strange errors.
This is because the tests in that suite are meant to be run serially, but are running in parallel, since that was left out of the config.  This PR fixes this by changing the Flaky test suite to serial

federation: Disable half baked APIs from federation

Fixes https://github.com/kubernetes/kubernetes/issues/42587
Disables batch and autoscaling APIs as we didnt get the controllers merged for them in time.

This is a fall back option in case https://github.com/kubernetes/kubernetes/pull/42225 is not approved by the release team.

We need one of this or https://github.com/kubernetes/kubernetes/pull/42225 to be merged in 1.6.

The design of DaemonSet requires a relist before each phase (manage,
update, status) because it does not short-circuit and requeue for each
action triggered.

The DaemonSet Listers still use selectors, because this is the
behavior expected by callers. This clarifies the meaning of the
returned list. Some callers may need to switch to using
GetControllerOf() instead, but that is a separate, case-by-case issue.

This is part of the completion of ControllerRef, as described here:

https://github.com/kubernetes/community/blob/master/contributors/design-proposals/controller-ref.md#watches

Now that DaemonSet adds ControllerRef to Pods it creates,
we need to set this default so legacy behavior is maintained.

[Bug Fix] Garbage Collect Node e2e Failing

This node e2e test uses its own deletion timeout (1 minute) instead of the default (3 minutes).
#41644 likely increased time for deletion.  See that PR for analysis on that.
There may be other problems with this test, but those are difficult to pick apart from hitting this low timeout.

This PR changes the Garbage Collector test to use the default timeout.  This should allow us to discern if there are any actual bugs to fix.

Create "framework" per upgrade test

There were already a few tests just using the default framework
namespace instead of creating a new one. Also there are several
testing libraries that use the default framework's default namespace
as well. It's just easier this way.
