[Bug 2028442] [NEW] Support DNS for ovn_{nb, sb}_connection

 

Public bug reported:

At the moment, it seems that when using a DNS hostname for
`ovn_nb_connection` or `ovn_sb_connection`, the connection never seems
to go up.

It seems that the `ovs` library does not resolve an IP address before
proceeding, I'm not sure if we should be resolving things and passing
them on resolved to OVS, or tryign to look for fix upstream.

This is pretty critical for HA deployments that rely on multiple
replicas with hostnames (i.e. a Kubernetes StatefulSet)
