Can a server instance that has a db in one existing bdr group add that same db to a different/new bdr group so that the
dbbelongs to two different bdr groups at the same time?
e.g.
node 1, db_x, bdr_group (node 1, node 2)
node 2, db_x, bdr_group (node 1, node 2) AND bdr_group(node 2, node 3)
node 3, db_x, bdr_group(node 2, node 3)
