powervc driver has no support for boot VM with pre-created neutron port

[Terry Yao]

There is no support for booting VM with a pre-defined neutron port, like use python CLI "nova boot --nic port-id=xxxxxxx". Need to get the PowerVC side's neutron port-id from the openstack-side's port-id, then pass down the port-id to PowerVC in nova-powervc's spawn methond.
