Galera MTR Tests: MW-308 , MW-307, GCF-992
* a dedicated test for wsrep_retry_autocommit * some galera_toi_* tests were only passing because wsrep_retry_autocommit was in effect. The tests were changed to do not use autocommit * higher timeout values in galera_2nodes.cnf , galera_3nodes.cnf Signed-off-by: Sachin Setiya <sachin.setiya@mariadb.com>
