Kaustubh Dhokte 73632416b3 Preserve kube-apiserver manifest params during upgrade-activate
This change a6a5349d02
(k8s-1.22.5: remove feature-gates)
adds a script that is run during upgrade activate. The script modifies
kubeadm cluster config and eventually updates kube-apiserver manifest
to remove deprecated features-gates in k8s 1.22.

As 'kubeadm init phase' is rerun in the script, it updates the
kube-apiserver manifest to be in sync with the  kubeadm cluster config.
In that process, it nullifies the effect of these two commits,
04a1c1b080
(Rework advertise address in apiserver-change-param)
and 52ace69c83
(Amend kube-apiserver 1.23 configuration to use PSP)

This change adds a function to the script that preserves the effect
of above listed commits.

Test Plan:
On CentOS AIO-SX
PASS: Upgrade Successful. Check if advertise address in
      kube-apiserver manifest before and after running
      upgrade-activate is same.
      Ensure that the seccomp profile configuration is
      removed after upgrade-activate.
      Kube-apiserver is running and cluster is accessible after
      the upgrade.
PASS: No Shellcheck errors
