CRI: Check nil pointer to avoid kubelet panic.
When working on the containerd kubernetes integration, I casually returns an empty `sandboxStatus.Linux{}`, but it cause kubelet to panic.
This won't happen when runtime returns valid data, but we should not make the assumption here.

[Federation] Disable the E2E test for federated replica set rebalancing
We are able to reproduce the flaky failure locally, and can debug without running this on the CI.
Automatic merge from submit-queue
[Federation] Create a unique label and label selector for each replica set created by the replica sets E2E test.
Previously, each replica set created would use the same pod labels and replica set label selectors, so tests run in parallel could conflict with each other. This ensures that each replica set test has its own set of pods to work with.
This should fix the currently-very-flaky E2E test for weighted federated replica set preferences.
When ctrl.kubeClient.Core().PersistentVolumes().Create(volume) returns no err, but storeVolumeUpdate() failed, we save PV sucessfully ,but here err is not nil,
we should not run the codes next in block if err != nil {}
same in the deletion retries below

Cleanup make test-integration
``make test-integration`` was using the first positional arg passed to ``WHAT`` to filter the list of integration test packages. This PR switches to passing ``WHAT`` verbatim to be consistent with how ``make test`` works. That means the new way to scope execution to a single integration package will be:
```bash
make test-integration WHAT="./test/integration/auth" KUBE_TEST_ARGS="-run=^TestKindAuthorization$"
```
Instead of:
```bash
make test-integration WHAT="auth -test.run=^TestKindAuthorization$"
```
This PR also ensures that the script exits after running a single test case and that etcd cleanup is not done twice at the end of a successful test run. Both were issues encountered while diagnosing the scoping issue.

Fixes MountVolume.NewMounter errors not displayed to users via describe events
Fixes#42004
This fixes the problem of mount errors being eaten and not displayed to users again. Specifically erros caught in MountVolume.NewMounter (like missing endpoints, etc...)
Current behavior for any mount failure:

Fix test for provisioning in unmanaged zone.
defer evaluates arguments of the deferred function immediately, so it actually
deleted a storage class and a claim before the test could do anything useful.
The test passed just accidentally, as the test is expected to time out. It
timed out from wrong reasons though.

Make kubelet never delete files on mounted filesystems
With bug #27653, kubelet could remove mounted volumes and delete user data.
The bug itself is fixed, however our trust in kubelet is significantly lower.
Let's add an extra version of RemoveAll that does not cross mount boundary
(rm -rf --one-file-system).
It calls lstat(path) three times for each removed directory - once in
RemoveAllOneFilesystem and twice in IsLikelyNotMountPoint, however this way
it's platform independent and the directory that is being removed by kubelet
should be almost empty.

Update NPD rbac.
I recently enabled NPD in gke.
However, I found that in gke e2e test (https://k8s-testgrid.appspot.com/google-gke#gci-gke), npd on the node could not talk with apiserver, and reported full of following errors:
```
E0324 05:08:26.745545 1328 manager.go:160] failed to update node conditions: the server does not allow access to the requested resource (patch nodes gke-bootstrap-e2e-default-pool-fd91d792-mqh4)

```
I created a GKE cluster (v1.7.0-alpha.0.1483+1e879c69ecf09e) myself, and found that addon manager could not create npd binding with the following error:
```
error: error validating "/etc/kubernetes/addons/node-problem-detector/standalone/npd-binding.yaml": error validating data: couldn't find type: v1alpha1.ClusterRoleBinding; if you choose to ignore these errors, turn validation off with --validate=false
```
I found that rbac was updated to beta, but npd was missed because it was merged after 9e6a3496b4 (diff-b05c70853d9a772b310db71a61297841).
I updated rbac to beta in the master manifest and npd on the node could talk with apiserver immediately.
We must get this in 1.6 to make NPD working. @dchen1107
