ResourceVersion values are opaque and math should not be done on them.
The intent of this test was to watch from a resourceVersion before the
moment where the objects were created, and we can find such a version by
listing from the API server before the tests begin.

This test wishes to observe a watch event. In order to do this in the
past, the test chose a well-known `Service` object, fetched it, and did
arithmetic on the returned `resourceVersion` in order to start a watch
that was guaranteed to see an event. It is not valid to parse the
`resourceVersion` as an integer or to do arithmetic on it, so in order
to make the test conformant to an appropriate use of the API it now:
- creates a namespace
- fetches the current `resourceVersion`
- creates an object
- watches from the previous `resourceVersion` that was read
This ensures that an event is seen by the watch, but uses the publically
supported API.
`ConfigMap`s are used instead of `Service`s as they do not require a
valid `spec` for creation and make the test terser.

- Also update test-cmd.sh to pass a signing ca to the kube controller
manager, so CSRs work properly in integration tests.

It was possible to patch images in the YAML files via KUBE_TEST_REPO, but it
was not possible to know in advance which images might be needed. Now
-list-images also includes all images referenced by the
test-manifest/storage-csi YAML files.
Upon reconsidering as to the purpose of the test i.e to test the lock
contention flags (--lock-file-contention and --lock-file), it makes
sense that we test only the actual functionality which is the kubelet
should stop once there is a lock contention.
In no way it is the responsiblity of the kubelet to restart, which would
be the responsiblity of a higher system such as systemd.
Hence the removal of the check for releasing the lock and checking for
whether the kubelet is healthy again or not seem out of scope from
kubelet's responsiblities.

Some storage tests deploy DaemonSets which hard-code /var/lib/kubelet as root
directory for kubelet registration and pod directory. There was already a
parameter which allowed specifying the root directory, just with a very
confusing name ("--volume-dir") and matching field name. A --kubelet-root-dir
parameters gets added because this may make it easier to find the parameter,
with the old name preserved as an alias for the same field for backwards
compatibility.
