Move manage.py to ara.server.__main__ and add an entry point

This moves manage.py inside the package and sets up an "ara-manage"
console entry point for doing something like "ara-manage runserver"
instead of "python manage.py runserver".

Putting this under __main__ also allows users to do "python -m
ara.server".
