Use the same pattern everywhere in the e2e test
harness, use busybox (from dockerhub) instead
of using the one from k8s.gcr.io registry.

Add e2e tests for volumeMode of persistent volume
This set of e2e tests is to confirm that persistent volume works well for all volumeModes.
Coverage of the tests are shown in the figure of [Test cases], below.
Once implementation policy is confirmed to be good, we can add plugins and test cases to this.
[Test cases]

Introduce scheduler CPU/Memory profile-gathering in density test
This should help us get more reliable/realistic data for scheduler (from our real-cluster scalability tests).

Split scheduler latency metric to fine-grained steps
This splits the summary metric we recently added into finer steps. It should be very useful for performance experiments.
/cc @wojtek-t
fyi - @bsalamat @misterikkit
Strictly speaking this is a breaking change, but since this metric was added only ~week ago I think it should fine (we should port this change to 1.11).

Split 'scheduling_latency_seconds' metric into finer steps (predicate, priority, premption)

Add e2e regression tests for the kubelet being secure
**What this PR does / why we need it**:
This PR does,
1. The kubelet cAdvisor port (4194) can't be reached, neither via the API server proxy nor directly on the public IP address
2. The kubelet read-only port (10255) can't be reached, neither via the API server proxy nor directly on the public IP address
3. The kubelet can delegate ServiceAccount tokens to the API server
4. The kubelet's main port (10250) has both authentication (should fail with no credentials) and authorization (should fail with insufficient permissions) set-up

Add reliable wait for volume server startup.
Remove sleep(20) and check for readiness of volume servers by checking logs.
**Special notes for your reviewer**:
I prefer checking logs over readiness probe, as it's not easy to probe for Ceph/iSCSI/NFS/Gluster server readiness.

e2e/storage: parameterize container images
**What this PR does / why we need it**:
The CSI integration test for hostpath was hard-coded to use the latest
stable release of the sidecar and hostpath container images. This
makes sense for regression testing of changes made in Kubernetes
itself, but the same test is also useful for testing the "canary"
images on quay.io before tagging them as a new release or for testing
locally produced images. Both is now possible via command line
parameters.

Related-to: kubernetes-csi/docs#23

Modified regional PD test to fetch template name from GCE
**What this PR does / why we need it**: Previously, the regional PD failover e2e test assumes a specific relationship between the names of an instance group and its corresponding template. It turns out to not always hold true for different types of clusters. Instead, the test should fetch the correct template name by calling out to GCE.
