Run a set of hbase tests. Individual tests may be specified on the

   -c          Run 'mvn clean' before running the tests
   -f FILE     Run the additional tests listed in the FILE
   -u          Only run unit tests. Default is to run 
               unit and integration tests
   -n N        Run each test N times. Default = 1.
   -s N        Print N slowest tests
   -H          Print which tests are hanging (if any)
   -e          Echo the maven call before running. Default: not enabled
   -r          Runs remotely, on the build server. Default: not enabled
