Make TestRaptorIntegrationSmokeTestMySql single threaded
Multiple tests running in TestRaptorIntegrationSmokeTestMySql can cause
MySQL deadlock. This is expected as different transactions can hold
locks in different orders. In production, this can also happen but with
less concern as we do not expect multiple write operations happening to
the same table.
