mariadb/mysql-test/suite/multi_source/gtid_ignore_duplicates.test
Kristian Nielsen 95e09f0766 MDEV-12179: Per-engine mysql.gtid_slave_pos table 
Intermediate commit.

Update multi_source.gtid_ignore_duplicates test to avoid a sporadic
failure following MDEV-12179 functionality.

The test case manually messes with the mysql.gtid_slave_pos table.
Make sure to clean up that at the end of the test, and suppress the
messages from the server about these changes.
