With this PR, the second call to `Acquire()` will block unless the lock is released (process exits).
Also removed the memory mutex in the previous code since we don't need `Release()` here so no need to save and protect the local fd.
Fix#42929.

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`.

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. This change ensures that the informer clears its
map of informers when Stop() is called to prevent a double close, and
that the test no longer adds the cluster twice.

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
```
