    Logout user if he has no valid tokens

    Before this patch, if user's rights were changed
    or revoked - there would be "Unauthorized" errors
    on every page since user had no rights to view them
    because he had no valid tokens in that case.

    Now user will be logged out if he has no valid tokens.
    Set `escalate` to True (for unauthorized-error)
    to always log user out.

    Also, now horizon.exceptions.NotAuthorized is a part of
    UNAUTHORIZED tuple in the exceptions.py, because this type
    of exception is re-raised after handling services unauthorized errors.
    Looks like it was missing. Now the horizon.exceptions.NotAuthorized
    is handled like all NotAuthorized exceptions.

    And horizon_middleware.py in process_exception now generates
    logout_reason for cases if user is not authorized.
