In the patch [1] we changed definition of the abstract method
"plug" in the LinuxInterfaceDriver class.
That broke e.g. 3rd-party drivers which still don't accept this
new parameter called "link_up" in the plug_new method.
So this patch fixes this to make such legacy drivers to be still working
with the new base interface driver class.
This commit also marks such definition of the plug_new method as
deprecated. Possibility of using it without accepting link_up parameter
will be removed in the "W" release of the OpenStack.
