Previously there were 4 python scripts being installed
into /usr/{local/}bin/ which contained the extension *.py.
There was also a developers script called barbican.sh
to create a developer's environment.
This change switches away from installing them as scripts,
preferring to use pbr's console_scripts entry point. This
means that the scripts were moved to be part of a 'cmd'
module within the barbican module.
The barbican.sh script is also no longer installed as it
seems inappropriate to install this on consumers machines.
A few cosmetic changes were added to achieve pep8.
