vrf: T6189: render FRR L3VNI configuration when creating VRF instance
When adding and removing VRF instances on the fly it was noticed that the vni statement under the VRF instance in FRR vanishes. This was caused by a race condition which was previously designed to fix another bug. The wierd design of a Python helper below the VRF tree to only generate the VNI configuration nodes is now gone and all is rendered in the proper place. (cherry picked from commit e7bb65894f86372dc0f6e8fd39b1628e0a224c68)
