* Add the ability to delete a given set of etcd snapshots from the CLI for locally stored and S3 store snapshots.

Problem:
Only the client CA is passed to the kube-controller-manager and
therefore CSRs with the signer name "kubernetes.io/kubelet-serving" are
signed with the client CA. Serving certificates must be signed with the
server CA otherwise e.g. "kubectl logs" fails with the error message
"x509: certificate signed by unknown authority".

Solution:
Instead of providing only one CA via the kube-controller-manager
parameter "--cluster-signing-cert-file", the corresponding CA for every
signer is set with the parameters
"--cluster-signing-kube-apiserver-client-cert-file",
"--cluster-signing-kubelet-client-cert-file",
"--cluster-signing-kubelet-serving-cert-file", and
"--cluster-signing-legacy-unknown-cert-file".

Add `.github/workflows/cgroup2.yaml` for running Fedora on Vagrant on
GitHub Actions to test cgroup2 environment.

Only very basic smoke tests are executed, as Vagrant is too slow to run
the entire sonobuoy.

The kube-apiserver cert should have the same SANs in the same order,
excluding the extra user-configured SANs since this will only be used
in-cluster.

Add html comments so that helper text is not shown when posting the feature request.

Configuration will be loaded from config.yaml and then config.yaml.d/*.(yaml|yml) in
alphanumeric order.  The merging is done by just taking the last value of
a key found, so LIFO for keys.  Slices are not merged but replaced.
