Add verbosity to the unit tests in activities

Presently the tests of the activities can be run as follows:
./setup.py check
./setup.py check unit
./setup.py integration

The verbosity of the unit tests being run is the default value, so I changed it and added the option of unit_verbose, which run the unit tests with higher verbosity, so that the user can understand more from the tests run...

./setup.py check unit_verbose

I can add screenshots to show the Terminal Results, if required

Please Review...
