Implement MAC Flush for BD or Interface from the L2FIB
Allow non-static MACs in the L2FIB which is associated with an
interface or a bridge domain (BD) be flushed. MAC flush are
initiated automatically when an interface is removed from a BD
or when a BD is deleted. MAC flush can also be invoked manually
via the following CLI:
l2fib mac-flush interface <if-name>
l2fib mac-flush bridge-domain <bd-id>
