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.

Add template attr. for subnet, router create in Nuage plugin

subnet create and router create commands now gives the ability
to the user to create subnets and routers via neutron cli with
additional attributes nuage_subnet_template and nuage_router_template
respectively. The instantiated subnet and router inherits the properties
of the template that was mentioned in the additional parameters.
