description |
As reported and fixed in [0] if the node that is configured with an empty ``--db-*-cluster-remote-addr`` is no longer the leader, the ovn-ctl script will hang on startup.
Prior to the hang the script will successfully start the ovsdb-server, but never get to the point where a clustered DB is upgraded in the event of a schema change.

[Impact]
On upgrades requiring schema changes a cluster may never be upgraded, this can be problematic and might in the worst case scenario lead to data plane outage.
Having said that it is not very likely that we will SRU changes to Focal that includes schema changes, but it is good to be on the safe side so we're ready for it in the event it happens.
[Test Plan]
1. With base in the ovn-central charm gate test we can deploy a OVN database cluster.
2. Restart services so that DB leader transition away from the machine that created the cluster.
3. Restart services again on original leader and confirm whether the bug is fixed.
[Regression Potential]
The patch in question has been in upstream branches and releases for a long time, it is also a very minor change adding a argument that allows control tool to not hang when the local unit is not the leader.
