Updates to Postgres Operator 3.5 to 4.3 Upgrade
Updates to Postgres Operator 3.5 to 4.3 Upgrade

This updates the 3.5 upgrade procedure to correct an issue
where jobs are not cleaned up correctly, adds an
additional procedure to rename an existing pgBackRest backup
repo PVC to match the updated naming convention in use by the
Postgres Operator version 4.3, adds additional handling for
clusters that have undergone a failover or restore event,
and does some general cleanup.
