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
We do not want to run the openstack hooks by default since neither the SQLite Metadata Storage driver nor the Disk Storage driver need anything provided by those two hooks.
