Subject: [PATCH] Switch firewalld state to use change_interface

firewalld.present state allows to bind interface to given zone.
However if the interface is already bound to some other zone, call-
ing `add_interface` will not change rebind the interface but report
error.
Option `change_interface` however can rebind the interface from one
zone to another.

This PR adds `firewalld.change_interface` call to firewalld module
and updates `firewalld.present` state to use this call.
