Alexander Kukushkin bba9066315 Make it possible to run pg_rewind without superuser on pg11+ (#1035) ...

* expose the current patroni version in DCS
* expose `checkpoint_after_promote` flag in DCS as an indicator that pg_rewind could be safely executed
* other nodes will wait until this flag is set instead of connecting as superuser and issuing the CHECKPOINT
* define `postgresql.authention.rewind` with credentials for pg_rewind in patroni configuration files.
* create user for pg_rewind if postgres is 11+
* grant execute on functions required for pg_rewind to rewind user
