Test Command

@evansde77 
First attempt at cirrus test command. Ran as 'git cirrus test' with an optional '--suit=NOSETESTS_ARGS'
So I would do this as:

```python
def nose_args(self, suitename):
      return self.get('test-{0}'.format(suitename), {})
```

and it will work for any old suite that people want to add
