[Federation] Fix flakey ingress unit test
The unit test for the ingress controller was previously adding a cluster twice, which resulted in a cluster being deleted and added back. The deletion was racing the controller shutdown to close
informer channels, sometimes resulting in closing an already closed channel. This change ensures that the federated informer clears its map of informers when ``Stop()`` is called to insure against a double close, and fixes the test to no longer add the cluster twice.
Targets #43009

Allow DaemonSet controller to PATCH pods, and add more steps and logs in DaemonSet pods adoption e2e test
DaemonSet pods adoption failed because DS controller aren't allowed to patch pods when claiming pods.
[Edit] This PR fixes#42908 by modifying RBAC to allow DaemonSet controllers to patch pods, as well as adding more logs and steps to the original e2e test to make debugging easier.
Tested locally with a local cluster and GCE cluster.

Move node and event observer helpers to e2e/common
**What this PR does / why we need it**:
Moves existing test helper functions in OIR e2e tests to `test/e2e/common`. These functions wrap informers to help test writers to observe events instead of long-polling for status updates.
For usage examples, see `test/e2e/opaque_resource.go`.

Fixed incorrect result of getMinTolerationTime.
For the following case, `getMinTolerationTime` should return one; but it returned -1 ：
1. for tolerations[0], TolerationSeconds is nil, minTolerationTime is not set
2. for tolerations[1], it's TolerationSeconds (1) is bigger than `minTolerationTime`, so minTolerationTime is still -1 which means infinite.
```

Fix DefaultTolerationSeconds admission plugin
DefaultTolerationSeconds is not working as expected. It is supposed to add default tolerations (for unreachable and notready conditions). but no pod was getting these toleration. And api server was throwing this error:
```
Mar 08 13:43:57 fedora25 hyperkube[32070]: E0308 13:43:57.769212 32070 admission.go:71] expected pod but got Pod

Mar 08 13:45:39 fedora25 hyperkube[32070]: E0308 13:45:39.754669 32070 admission.go:71] expected pod but got Pod

```
The reason for this error is that the input to admission plugins is internal api objects not versioned objects so expecting versioned object is incorrect. Due to this, no pod got desired tolerations and it always showed:
```
Tolerations: <none>
```
After this fix, the correct tolerations are being assigned to pods as follows:
```
Tolerations: node.alpha.kubernetes.io/notReady=:Exists:NoExecute for 300s
node.alpha.kubernetes.io/unreachable=:Exists:NoExecute for 300s
```

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!)
