MXS-1509: Initial implementation of test case

Browse Source 
Added some code to detect server states in a consistent manner and created
the test. The multi-source replication appeared to cause problems for the
test system which needs to be resolved.

Added --force flags to most direct `mysql` calls to prevent errors from
stopping the processing of remaining commands.
