Public bug reported:

Right now, every IDL instance of the Southbound database(minus the
maintenance worker) is monitoring the MAC_Binding table [0]. This table
can increase a in size overtime and substantially increasing the memory
used to keep an in-memory replica of this table in memory for each SB DB
IDL.

We need to find a way to optimize this aspect in ML2/OVN and lower the
memory usage for the driver.
