Issues with ETCD-backup-Policy

[ch-stark]

Issues have been reported, policy will be reviewed, tested and updated

@ch-stark I did not have the reported problem with the commands being re-ordered using our 2.4.1. build. I'm not sure yet if the policy functions as expected. I did have to make some additional edits:

1. The ClusterRoleBinding points to a service account and the namespace for that service account was needed.
2. Some of the policy that I copied and pasted ended up missing. It was the volumes for the job. Keep an eye out to see if you see that too.

Working on a simpler policy

I tried getting this working and never made good progress. I suspect we would need to decide if we can have someone focus on fixing this policy.

Today Christian let me know that the policy linked in comment https://github.com/stolostron/policy-collection/issues/199#issuecomment-1021229256 was a good solution -- tried by someone that gave good feedback. It does involve a custom image that needs to be created that goes along with the policy. So need to decide if we want that to be created under stolostron.

The nice solution here is currently Tech Preview: https://access.redhat.com/documentation/en-us/openshift_container_platform/4.14/html/backup_and_restore/control-plane-backup-and-restore#creating-automated-etcd-backups_backup-etcd
