Critical operation PDB (#2830)

Browse Source 
Create the second PDB to cover Pods with a special "critical operation" label set.

This label is going to be assigned to all pg cluster's Pods by the Operator during a PG major version upgrade, by Patroni during a cluster/replica bootstrap. It can also be set manually or by any other automation tool.
