First pass implementation of support for virtual MAC address

This change introduces a new parameter named "interface" under the
vrrp-group configuration tree under ethernet interfaces and vlans.  If
the "interface" parameter is set, keepalived will be configured to
bring up a macvlan interface, which will hold the virtual MAC address
that is specified in the VRRP spec.
