This patch creates a new driver using NB DB information instead of SB DB. This has 2 objective: - Alleviate the stress on big scale environment due to many connections to the SB DBs. - Being more future proof as content generated in the SB DBs based on NB DB information is subject to change. For example we were already adviced that the information we are currently using for ovn LB events at the SB DB is probably going to change soon. Depends-On: https://review.opendev.org/c/openstack/ovsdbapp/+/873853 Change-Id: Ib6bf077ce1e354652f5b728bd7192c762d3d071b

This patch introduces a new driver that instead of connecting to the OVN
|
|
SB DB to watch for relevant events, it connects to the OVN NB DB. The main
|
|
reasons for doing so are: 1) scalability purposes; and 2) rely on the
|
|
stable fields offered by the NB DB, instead of the SB DB that may change
|
|
any time and break our watchers logic (as it has already happened with the
|
|
OVN Load_Balancer table and its datapath field usage).
