HBASE-25151 warmupRegion frustrates registering WALs on the catalog replicationsource

warmupRegion called by Master on Region move will instatiate
the meta WALProvider as part of its action making it so
it is already created by the time we go to open the
hbsae:meta Region. Accommodate meta walProvider
being already up.

hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/handler/AssignRegionHandler.java
hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/handler/UnassignRegionHandler.java
 Pass regionInfo. Needed internally.

hbase-server/src/main/java/org/apache/hadoop/hbase/replication/regionserver/ReplicationSourceManager.java
 Add handling if meta wal provider already instantiated when
 addCatalogReplicationSource runs.

hbase-server/src/test/java/org/apache/hadoop/hbase/replication/regionserver/TestMetaRegionReplicaReplicationEndpoint.java
 Add exercising moving meta around between servers. Test replication
 keeps working.
