Steps to reproduce:
1. add ipv4 address to interface:
"ietf-ip:ipv4": {"address": [

{"ip": "192.168.0.2", "netmask": "255.255.255.0"}

]}
2. remove the address and add a new one in a single PUT request:
"ietf-ip:ipv4": {"address": [

{"ip": "192.168.0.3", "netmask": "255.255.255.0"}

]}
The new address is added before the old one is deleted. The delete operation should be completed first.

3. get operational interface data:
"ietf-ip:ipv4":{}
4. get VPP ip adddress dump:
192.168.0.2/24
If the two addresses cannot be configured together (e.g. they are on the same subnet), this causes desync between VPP state and HC operational data.
