    Correct Neutron RabbitMQ User Param Mapping

    Changed parameter mapping for RabbitMQ user name
    overrides. THT maps the user name override to
    neutron::rabbit_user for the Neutron service only.

    This will allow the transport_url string to be built
    correctly when a deployer wishes to override the default
    guest username.
