Description of problem:
When deploying an OSP 17 overcloud with OVN DVR AND RAFT, the logs show "Overcloud Deployed successfully", but there are some issue with Octavia.

This issue appears to be related to [1].
I changed the ovn_nb_connection variable in octavia.conf to port 6641 on controller's IP on each controller host, instead of port 6641 on internal API VIP which was what it was set to before. Running "podman restart octavia_api" after that seemed to fix the issue.

I noticed that the patch [2] adds a deployment parameter ovn_db_host which defaults to hiera('ovn_dbs_vip'). I think, in the case of deployments with RAFT, the deployment should detect that RAFT is enabled and change the value of this parameter automatically.
[3] has sosreports from the controllers when ovn_nb_connection was set to port 6641 on the internal API VIP.
[4] has sosreports from the controllers after ovn_nb_connection was set to port 6641 on the controller IPs.
