The `apparmor_parser` binary is not really required for a system to run
AppArmor from a Kubernetes perspective. How to apply the profile is more
in the responsibility of lower level runtimes like CRI-O and containerd,
which may do the binary check on their own.
This synchronizes the current libcontainer implementation with the
vendored Kubernetes source code and allows distributions to use
AppArmor, even when they do not have the parser available in
`/sbin/apparmor_parser`.

The server service monitors the kubelet service and restart it
once the service is down, to avoid kubelet double restarting
we will stop the kubelet service and wait until the kubelet will be
restarted and the node will be ready.

e2e test validates the following service status endpoints
- patchCoreV1NamespacedServiceStatus
- readCoreV1NamespacedServiceStatus
- replaceCoreV1NamespacedServiceStatus
Also includes untested service endpoint
- patchCoreV1NamespacedService
The same SHA cannot be pushed twice to the staging registry. Because some images were
mirrored, their SHAs remained unchanged. This addresses this issue.
Sharing the same connection for multiple streams should have worked,
but ran into unexpected timeouts:

Instead of trying to use the client-go portforward package as-is it is
simpler to copy some code from it and then use the http stream
directly. That way we don't need to go through a local listening
socket and error handling and logging becomes simpler.
This replaces embedding of JavaScript code into the mock driver that
runs inside the cluster with Go callbacks which run inside the
e2e.test suite itself. In contrast to the JavaScript hooks, they have
direct access to all parameters and can fabricate arbitrary responses,
not just error codes.
Because the callbacks run in the same process as the test itself, it
is possible to set up two-way communication via shared variables or
channels. This opens the door for writing better tests. Some of the
existing tests that poll mock driver output could be simplified, but
that can be addressed later.
For now, only tests using hooks use embedding. How gRPC calls are
retrieved is abstracted behind the CSIMockTestDriver interface, so
tests don't need to be modified when switching between embedding
and remote mock driver.
The function must modify the content of the "creds" pointer, not the
pointer.
