The test did not use the wait_for_monitor function to sync with the
monitor. This function speeds up the testing greatly by removing
unnecessary sleeps from it.
Also reduced the amount of data inserted into the cluster. There's no real
need to test with large amounts of data as it is only a functional test.
The mm test was on the heavy side and the workload can be reduced for the
sake of testing only the functionality.
The mm_mysqlmon test did not check the initial state of the
server. Although not necessary, adding it will help detect test failures
caused by broken replication.
mxs1457_ignore_deleted did not stop the monitors before breaking the
replication and attempting to use MaxScale. As the test expects
authentication to work regardless of the actual state of the servers, the
monitors need to be disabled before a query is attempted.
