mcast_last_member_count and also try to change them.

TEST: Vlan mcast_last_member_count global option default value      [ OK ]
TEST: Vlan mcast_last_member_interval global option default value   [ OK ]
TEST: Vlan 10 mcast_last_member_count option changed to 3           [ OK ]
TEST: Vlan 10 mcast_last_member_interval option changed to 200      [ OK ]
