During a K8s feature upgrade from 1.23 to 1.24 we need to remove
the "RemoveSelfLink=false" feature gate from kube-apiserver.
We had previously handled updating the kubeadm configmap, which
was sufficient to handle the running system. However, in order
to properly handle backup and restore after the K8s upgrade to
1.24 (and just for general tidiness) we need to also remove the
feature gate from the saved service parameters and from the
last_kube_extra_config_bootstrap.yaml file.
It's possible that there are other kube-apiserver feature gates
specified by the end user, this adds a bit of complexity to the
code.
Test Plan:
PASS: Test python script and bash script in isolation.
PASS: End-to-end test with k8s upgrade and backup/restore with
manual modification of service parameters and yaml file.
Tested with AIO-DX, AIO-SX unoptimised restore, and
AIO-SX optimised restore.
PASS: K8s upgrade using the new code, ensure service parameter
and last_kube_extra_config_bootstrap.yaml have been
updated with "RemoveSelfLink=false" feature gate removed.
