(WIP) Test Command

@evansde77 
First attempt at cirrus test command. Ran as 'git cirrus test' with an optional '--suit=NOSETESTS_ARGS'
honestly, I would just throw an exception that says "No such test suite defined in cirrus.conf: {0}  expected to find section named [test-{0}] in config.".format(suite) here, since it needs something defined.
