- Register the new file in /certs/renewal, so that the
file is renewed if present. If not present the common message "MISSING"
is shown. Same for other certs/kubeconfig files.
- In /kubeconfig, update the spec for admin.conf to use
the "kubeadm:cluster-admins" Group. A new spec is added for
the "super-admin.conf" file that uses the "system:masters" Group.
- Add a new function EnsureAdminClusterRoleBinding() that includes
logic to ensure that admin.conf contains a User that is properly
bound on the "cluster-admin" built-in ClusterRole. This requires
bootstrapping using the "system:masters" containing "super-admin.conf".
Add detailed unit tests for this new logic.
- In /upgrade#PerformPostUpgradeTasks() add logic to create the
"admin.conf" and "super-admin.conf" with the new, updated specs.
Add detailed unit tests for this new logic.
- In /upgrade#StaticPodControlPlane() ensure that renewal of
"super-admin.conf" is performed if the file exists.
Update unit tests.
Back up kubelet config file for `kubeadm upgrade apply`, some code
refactoring is done to de-dup some redundant code logic.

Currently, there are some unit tests that are failing on Windows due to
various reasons:
- filepath.IsAbs does not consider "/" or "\" as absolute paths, even
though files can be addressed as such.
- paths not properly joined (filepath.Join should be used).
- files not closed, which means that they cannot be removed / renamed.
- some assertions fail due to slashes / backslashes not matching.
- backslashes need to be escaped in yaml files, or put between ''
instead of "".
During "upgrade node" and "upgrade apply" read the
kubelet env file from /var/lib/kubelet/kubeadm-flags.env
patch the --container-runtime-endpoint flag value to
have the appropriate URL scheme prefix (e.g. unix:// on Linux)
and write the file back to disk.
This is a temporary workaround that should be kept only for 1 release
cycle - i.e. remove this in 1.25.
Used T.Run API for kubeadm tests in app/phases/selfhosting and
app/phases/update directories
This should improve testing output and make it more visible
which test is doing what.
