###############################################################################
# Validate that XA transactions can be prepared on a group primary (server1)
# and committed on a different primary (server2) after a failover.
# Also validate that the old primary (server1) can rejoin the group as a
# secondary and commit the XA transaction that it did prepare.
# Both situations happen while the old primary (server1) keep the
# client session that did the XA PREPATE active.
#
# Test:
# 0. The test requires two servers: M1 and M2.
# 1. Bootstrap a group with server1 as the primary.
# 2. Join server2 to the group.
# 3. Do the XA PREPARE on the initial primary (server1)
# 4. server1 will leave the group, server2 will be elected
# primary.
# The client session that did the XA PREPARE will remain
# active.
# 5. server2 is the new primary, the XA transaction will be
# resumed on it.
# This mimics a load balancer behavior.
# 6. server1 rejoins the group, now as a secondary, it will
# receive the XA COMMIT through distributed recovery.
# 7. Clean up.
