    VPNaaS: Enable UT cases with newer oslo.messaging

    Now that 1.4.0.0a3 of oslo.messaging has been added to Neutron
    requirements, the unit test cases in VPNaaS code can be
    uncommented and included in the tests. These tests ensure that
    the correct validator is called, when validation is performed.
    This adds similar tests to the reference and Cisco VPNaaS
    implementation.
