    [OVN] Reduce the number of watched tables in MetadataProxyHandler

    This patch changes the SB IDL from the MetadataProxyHandler class to
    only watch the two required tables for it to function.

    The more tables it monitors, the bigger the burden is on the OVSDB to
    keep all the in-memory replicas updated. In special, the Chassis table
    can generate a lot of events due to the agents health check mechanism
    in the OVN driver so, removing it will prevent many events from being
    sent across the fabric.
