TVD: update port migration for V -> T instances
The patch does the following:
1. set instance vNIC to a common network interface
2. Live migrates to T cluster
3. Updates the instance vNIC to opaque network
Example:
nsxadmin -r ports -o nsx-migrate-v-v3 \
--property project-id=01dd52ff4c7047f79f6259f916c83790 \
--property host-moref=host-11 --property respool-moref=resgroup-9 \
--property datastore-moref=datastore-22 \
--plugin nsxv3
There is also an option to use net-name. The default here is 'VM Network'
