MDEV-7106: Sporadic test failure in multi_source.gtid MDEV-7153: Yet another sporadic failure of multi_source.gtid in buildbot This patch fixes three races in the multi_source.gtid test case that could cause sporadic failures: 1. Do not put SHOW ALL SLAVES STATUS in the output, the output is not stable. 2. Ensure that slave1 has replicated as far as expected, before stopping its connection to master1 (otherwise the following wait will time out due to rows not replicated from master1). 3. Ensure that slave2 has replicated far enough before connecting slave1 to it (otherwise we get an error during connect that slave1 is ahead of slave2).
