    Remove the traceback added by oslo-messaging RPC

    Remove the traceback added by oslo-messaging RPC, to avoid
    displaying traceback to user.

    Some requests that return traceback w/o this patch, now normal:
    $ openstack congress policy row list bob p
    Not Found::table 'p' doesn't exist (HTTP 404) (Request-ID: req-54c2a117-0306-4fd2-8d71-8f7e6d130a43)
    $ openstack congress policy rule list bob
    The specified policy does not exist.::Policy ID bob does not exist
    (HTTP 400) (Request-ID: req-d85db619-afa0-4977-99f8-0dc88c5daa0c)
    $ openstack congress policy delete bob
    Policy Name or ID 'bob' does not exist (HTTP 404) (Request-ID: req-e1a70735-f469-4fae-b278-f061b64f4298)
    $ openstack congress policy show bob
    Resource bob not found (HTTP 404)

    The 400 error should be addressed in separate patch.
