[RFE] Add support for binding activate and deactivate in sriov mechanism driver

[Adrian Chiris]

this RFE is required to complete the following Nova blueprint:
https://blueprints.launchpad.net/nova/+spec/libvirt-neutron-sriov-livemigration

Spec: https://github.com/openstack/nova-specs/blob/master/specs/stein/approved/libvirt-neutron-sriov-livemigration.rst

As the change builds on multiple port binding feature, its required that sriovnicswitch agent to support binding_activate() and binding_deactivate() callbacks.

The proposed changes to sriovnicswitch agent are:

- Implement binding_activate() and binding_deactivate() methods in agent.
- Configure agent to listen on the relevant topics.
- RPC version bump on agend side.
- When processing an activated binding treat it as a newly added port.
- Deactivated binding will trigger a NO-OP as once a binding is
  deactivated it will be removed by Hypervisor.
