Uncap concurrency in tests

This is 2 changes:

* Run dstat in unit test jobs so that we can get an idea of
  system performance/utilization.

* Remove the stestr concurrency cap.  With 8 cores, we have
  enough headroom to run the test dependencies (sql/zk) while
  the tests are running too.  Use all the CPU that's available.
