Public bug reported:

OVN metadata agent runs on each compute node in the cluster and creates
an SB DB connection per worker. In large scale deployments this may
cause a lot of load on OVN DBs. This bug is to improve OVN metadata
agent in a way it won't need connection to the OVN DB leader node but
will provide possibility to connect to follower nodes but it will
require OVN agent to not perform any writes, because the follower nodes
run in read-only mode too.
