Entry point should be compatible with setuptools

[Sidnei da Silva]

commandant.entry_point cannot be used as a real setuptools entry point, since it takes arguments unconditionally. Entry points need to take arguments at least conditionally, and introspect sys.argv if not passed arguments. Also, it should be declared as a console_script in setup.py

Sidnei:

Thanks a lot for the bug report. The entry point has to take
argument unconditionally, because they get passed to whatever
command is being run. Do you have any advice on what to do about
this issue?
