This test has been flaking. The current working theory is that
volume stats collection didn't run in time to grab the metrics
from the newly created pod.
Made the following changes:
- Added more logs to help debug future failures
- Poll metrics a few additional times before failing the test

Allow kubelet metrics tests to run on gke
**What this PR does / why we need it**:
On GKE, you can still access kubelet metrics, so allow the kubelet metrics test.

Fixing E2E Test - After restarting kubelet test expects node's status to be NotReady
**What this PR does / why we need it**:
This PR is fixing the e2e tests involves restarting the kubelets. After the kubelet is restarted, test expect the desired state to be NotReady.
After restarting the kubelet we should wait for some time and then check nodes status to be Ready.
Node should not be checked for NotReady state, after restarting kubelet.

e2e test for local storage mount point
**What this PR does / why we need it**:
We discovered that kubernetes can treat local directories and actual mountpoints differently. For example, https://github.com/kubernetes/kubernetes/issues/48331. The current local storage e2e tests use directories.
This PR introduces a test that creates a tmpfs and mounts it, and runs one of the local storage e2e tests.
**Which issue this PR fixes**: fixes https://github.com/kubernetes/kubernetes/issues/49126
**Special notes for your reviewer**:
I cherrypicked PR https://github.com/kubernetes/kubernetes/pull/50177, since local storage e2e tests are broken in master on 2017-08-08 due to "no such host" error. This PR replaces NodeExec with SSH commands.
You can run the tests using the following commands:
```
$ NUM_NODES=1 KUBE_FEATURE_GATES="PersistentLocalVolumes=true" go run hack/e2e.go -- -v --up
$ go run hack/e2e.go -- -v --test --test_args="--ginkgo.focus=\[Feature:LocalPersistentVolumes\]"
```
Here are the summary of results from my test run:
```
Ran 9 of 651 Specs in 387.905 seconds
SUCCESS! -- 9 Passed | 0 Failed | 0 Pending | 642 Skipped PASS
Ginkgo ran 1 suite in 6m29.369318483s
Test Suite Passed
2017/08/08 11:54:01 util.go:133: Step './hack/ginkgo-e2e.sh --ginkgo.focus=\[Feature:LocalPersistentVolumes\]' finished in 6m32.077462612s
```
**Release note**:
`NONE`
LocalVolumeType tmpfs added
Added checks to ensure tha volume created during setup contains expected testFileContent
Refactored tests out to avoid code duplication
Two different tests are performed with tmpfs:
-serial write and read in two different pods
-write and read in two different pods mounted at the same time

- Volume management on datastore (Create/Delete)
- Volume management on Virtual Machines (Attach/Detach)
- Storage Policy Management
- vSphere Cloud Provider changes to implement the cloud provider interfaces by calling into VCLib package.
- Modifications to e2e tests to accomodate the latest design changes.

Fix local storage test failures
**What this PR does / why we need it**:
Fixed a few issues:
- CI environment on GCE cannot resolve node names, need to use IPs. Use a different SSH wrapper that will get the IPs from the node object.
- Use hostdir instead of containerdir now that commands are executed directly on the host, instead of through a container.
- Get the PVC object again after it is bound so that it has the PV name.

Add basic install and mount flexvolumes e2e tests
fixes https://github.com/kubernetes/kubernetes/issues/47010
These two tests install a skeleton "dummy" flex driver, attachable and non-attachable respectively, then test that a pod can successfully use the flex driver. They are labeled disruptive because kubelet and controller-manager get restarted as part of the flex install. IMO it's important to keep this install procedure as part of the test to isolate any bugs with the startup plugin probe code.
There is a bit of an ugly dependency on cluster/gce/config-test.sh because --flex-volume-plugin-dir must be set to a dir that's readable from controller-manager container and writable by the flex e2e test. The default path is not writable on GCE masters with read-only root so I picked a location that looks okay.
In the "dummy" drivers I trick kubelet into thinking there is a mount point by doing "mount -t tmpfs none ${MNTPATH} >/dev/null 2>&1", hope that is okay.
I have only tested on GCE and theoretically they may work on AWS but I don't think there is a need to test on multiple cloudproviders.
