Description of problem:
We currently do not have the DBs in the must gather, which is pretty much required for debugging OVN issues. We need to include this when we pull the must gather.
After some digging it seems that the functionality we're looking for has already been implemented here (https://github.com/openshift/must-gather/blob/master/collection-scripts/gather_network_logs). Specifically we need to copy the OVN NB and OVN SB databases along with dumping the OVS ports as can be seen here (https://github.com/openshift/must-gather/blob/master/collection-scripts/gather_network_logs#L54) and here (https://github.com/openshift/must-gather/blob/master/collection-scripts/gather_network_logs#L67).
However for some reason the collection scripts for OVN and networking in general are not called by the main gather script here (https://github.com/openshift/must-gather/blob/master/collection-scripts/gather#L40) I am currently building my own must gather image and making sure everything checks out on a cluster bot 4.6 OCP cluster before I make a PR for activating the extra collection scripts
The following PR should remedy this https://github.com/openshift/must-gather/pull/169
