NSXv3: Add support for trunk service driver
This patch adds support for trunk extensions in the NSXv3
plugin.
Now you can create trunk and subports which map to CIF
on the backend.
i.e. trunk port <-> parent port and subport <-> child port
on the backend.
If backend fails to update subports, the status of trunk will be set
to ERROR.
Use OSC commands for trunk CRUD operations.
For e.g.
Create trunk with a subport:
openstack network trunk create --parent-port <parent-port>
--subport port=child-port,segmentation-type=vlan,segmentation-id=200
TRUNK_NAME
Delete trunk:
openstack network trunk delete TRUNK_NAME
