The patch adds NVP advanced LBaaS service support for NVP with
VCNS:
* NVP LBaaS 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
LB service On the vshield edge
* NVP LBaaS service plugin still uses LBaaS DB service logic,
while finally calling vShield Edge to support FWaaS service
- When creating VIP object, service attaches the object to
the advanced router with routedserviceinsertion service.
Then before pushing VIP VCNS call, the server would first
pushing associated POOL VCNS call and associated Monitor
VCNS call to vShield Edge. Deleting VIP is opposite
operation
- Refering to CUD operation of other objects, service would
first find the associated VIP object and then find the edge bound to
the router which vip inserted. Then service would push corresponding
VCNS call to Vshield Edge
* 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
