Drop nose dependencies

Horizon test setting no longer depends on nose and related stuffs.
This commit cleans up nose related dependencies.

The change was made in horizon Rocky-3,
so horizon 14.0.0.0b3 is required at least.

The command line to invoke UT in tox.ini is updated accordingly:
* --ignore-files=masakaridashboard/test/uuidsentinel.py is unnecessary
  as this file does not include test cases.
* --verbosity 2 is added to watch the test progress.
* Duplicated {posargs} in 'coverage' env is fixed.
* --exclude-dir in 'coverage' env is dropped as the corresponding
  directory does not exist.
