This bug is a sibling of the one it was cloned from to represent work needed in the OVN Octavia provider driver in order to maintain parity with the Amphora driver as this RFE is implemented.

+++ This bug was initially created as a clone of Bug #1813559 +++

There are use-cases where a load balancer should have multiple VIP addresses allocated from the same Neutron network. Users can specify additional subnet_id/ip_address pairs to bring upon the VIP port. This will allow for situations like having an LB with both IPv4+IPv6 or being exposed to both public and private subnets.

This would extend the load balancer API to support it. Example:

"additional_vips": [
  {
    "ip_address": "10.0.0.2", # This is optional
    "subnet_id": "a0304c3a-4f08-4c43-88af-d796509c97d2"
  },
]
