      Description

      To solve the ability to handle a replication delay (async or galera) in a variety of replication topologies, without an application needing to know the topology (beyond reader/writer nodes), MASTER_GTID_WAIT should wait for both async and galera GTID replication to be applied.

      The WSREP_LAST_WRITTEN_GTID/WSREP_LAST_SEEN_GTID/ WSREP_SYNC_WAIT_UPTO_GTID that got dumped in MariaDB 10.4/ Galera-4 fails to consider async replication topologies exist with Galera or understand the deep frustration in MDEV-20720 nor does it try to correct it (https://github.com/MariaDB/server/pull/1317).

      10.4 target based on Rasmus Johansson comment https://lists.launchpad.net/maria-developers/msg11691.html.
