The patch adds advanced FWaaS service support for NVP with
VCNS:
* NVP FWaaS is an advanced Service of NVP depending on NVP
advanced service router
- Once an advanced router id created, one corresponding
vshield edge will be deployed, and then we can configure
FW service on the vshield edge
* NVP FWaaS service plugin still uses FWaaS DB service logic,
while finally calling vShield Edge to support FWaaS service
- When firewall object is created, we will attach the
object to the advanced router with routedserviceinsertion_db
service
* on driver part, the driver will first convert the object
to VSM known object input, and then send a synchronous JSON
calling to VSM, and receive the result
