MXS-1509: Initial implementation of test case

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.
