@ArtRand I believe this _is_ testing the worker tasks: (L.572) the
`setBackend()` method creates a MesosCoarseGrainedSchedulerBackend, L.577-579
creates the requirements for an Executor, (L. 580) backend.resourceOffers()
looks for an offer that matches the requirements and launches an Executor task.
There is a separate unit test above, in MesosClusterSchedulerSuite.scala,
which checks for the labels in the driver itself.
