Fix up flavor_rxtx RBAC tests

[Felipe Monteiro]

flavor_rxtx compute tests should be re-written to offer coverage for the APIs listed in [0] and should check for the existence of the key in the response body or else raise a RbacMalformedResponse Exception.

    Fix flavor_rxtx_rbac

    Updates flavor_rxtx to more thoroughly test policy enforcement
    by
    - making use of RbacMalformedResponse to ensure rxtx_factor
      is included in response body
    - adding new flavor_rxtx tests

    Currently, POST /flavors is not tested as that action also
    enforces os-flavor-manage: create, which is admin-only by
    default and would therefore fail due to conflicting policy
    restrictions. This test will be added once multi-policy
    support is available.
