ovn southdb connection information is not being set in octavia.conf

[Felipe Reyes]

Octavia needs to talk to ovnsdb since ovn-octavia-provider 1.1.0[0], the charm is only configuring the information to talk to ovnndb.

This is what octavia-driver-agent daemon is logging on focal-yoga when ovn-chassis is related to octavia:
