The new etcd balancer (>3.3.14, 3.4.0) uses an asynchronous resolver for
endpoints. Without "WithBlock", the client may return before the
connection is up.

This makes sub packages of e2e test framework to use log functions
of core framework instead for avoiding circular dependencies.
NOTE: test/e2e/framework/ssh will make circular dependencies if
updating it. It is necessary to solve the issue in advance
before this work.
The assumption so far was that all drivers support read/write
volumes. That might not necessarily be true, so we have to let the
test driver specify it and then test accordingly.
Another aspect that is worth testing is whether the driver correctly
creates a new volume for each pod even if the volume attributes are
the same. However, drivers are not required to do that, so again we
have to let the test driver specify that.
After deleting a pod, we need to be sure that it really is gone,
otherwise there is a race condition: if we remove the CSI driver that
is responsible for the volume used by the pod before the pod is
actually deleted, deleting the pod will fail.
Once we have deleted the pod and the volume, we want to be sure that
NodeUnpublishVolume was called for it. The main motivation was to
check this for inline ephemeral volumes, but the same additional check
also makes sense for other volumes.
We need the 1.2.0 driver for that because that has support for
detecting the volume mode dynamically, and we need to deploy a
CSIDriver object which enables pod info (for the dynamic detection)
and both modes (to satisfy the new mode sanity check).
This ensures that the files are in sync with:
hostpath: v1.2.0-rc3
external-attacher: v2.0.1
external-provisioner: v1.3.0
external-resizer: v0.2.0
external-snapshotter: v1.2.0
driver-registrar/rbac.yaml is obsolete because only
node-driver-registrar is in use now and does not need RBAC rules.
mock/e2e-test-rbac.yaml was not used anywhere.
The README.md files were updated to indicate that these really are
files copied from elsewhere. To avoid the need to constantly edit
these files on each update, <version> is used as placeholder in the URL.
Moving pod related functions from e2e/framework/pv_util.go to
e2e/framework/pod in order to allow refactoring of pv_util.go into its
own package.

it turns out that the framework.TestContext.IPFamily variable is
not available for the DNS tests if they don't run in the initial
Ginkgo node when running in parallel.
We add a function to the framework to allow us to run command
only once per each Ginkgo node parallel execution.
It also adds a method to detect if the cluster is IPv6.
The use of the framework.TestContext.IPFamily variable guarantees
consistency all over the testing because this variable is only
assigned at the beginning of the testing.
