Falcon transport

TODOs:
    From review comments
DONE:
    validation has been ported over
    config management
    deuce-server console script
    hooks
    error management
    Logging is setup.
    Configspec added to validate inputs in config.ini

Note:
Travis will not pass, until we get the falcon functional tests in.
Its supposed to be the homedoc, something like zaqar's home doc. https://github.com/openstack/zaqar/blob/master/zaqar/queues/transport/wsgi/v1_0/homedoc.py

Right now, we return a 200 with an empty dict.
We need a story for that, which returns an actual home doc.
