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
