parallelizing a test in HiveQA

[Sergey Shelukhin]

Hi. After the branch merge, we’d like the newly added CliDriver test to be
parallelized like other such tests.
What do we need to provide for this to be configured? The test name is
TestMiniLlapCliDriver; it currently uses the same variable as some other
test in testconfiguration.properties, but I was going to change that.
