Add MAC binding aging mechanism, that should take care of stale MAC bindings.
The mechanism is configurable per logical router, with option called "mac_binding_age_threshold", which is 0 by default. The zero also indicates that the aging mechanism is disabled. The aging is based on timestamp in MAC_binding table, rows that exceed threshold specified by the LR option will be deleted. The row timestamp is refresh when we receive ARP that changes MAC address of corresponding row. Add config option for limiting how many MAC binding rows can be removed in single transcation called "mac_binding_removal_limit". The default value is 0 which is unlimited. The MAC binding aging won;t work, even if configured, unless all ovn-controllers support the MAC binding timestamp addition/update.
