Combine roles

Combined the 3 roles into 1 to make it easier to read/follow

add development task to run `manage.py start` at the end of the app code install. Running `manage.py add_admin` is still a manual process.

Fixed the development and staging tagged tasks to install dev-requirements.txt and tests-requirements.txt. This can be toggled on/off in the vagrant file when testing the appamor profiles.
@david415 did that to match the torrc file. But we do want to normalize all the other values and the in the tasks folder include .yml files need to be renamed to be reflective of what they are now.
