Public bug reported:

While trying to test out ovn-octavia-provider in devstack, I copied the
functional testing vars, e.g.

 OVN_BRANCH: v20.06.0
 OVS_BRANCH: v2.13.0

However, in devstack the octavia-driver-agent keeps crashing with a
trace like this

ERROR octavia.cmd.driver_agent Traceback (most recent call last):
ERROR octavia.cmd.driver_agent   File "/opt/stack/octavia/octavia/cmd/driver_agent.py", line 65, in _process_wrapper

ERROR octavia.cmd.driver_agent     assert table_name in schema.tables
ERROR octavia.cmd.driver_agent AssertionError
ERROR octavia.cmd.driver_agent

After a bit of debugging, I found out that it is trying to get the
'Load_Balancer' table in the SB database, which is a recent commit[1] in
v20.12.0

Not sure if this is a valid bug, but if the tests can be incremented to
a working version of OVN that might help prevent others from tripping
over this case. Thanks!
