Description of problem:
Sometimes, a system administrator knows positively that a given interface has a
better or worse preference as a default route.  For instance, my laptop has a
wireless card, and 2 onboard ethernet, and a docking station ethernet.  Thus,
the desired effect is that we want any hard-wired interface to get a default
route, and a wireless to get a default route - at a higher metric.  That way, if
the wireless is the only connection, it will take the default, but if a wired
interface comes up as well, that will take the load.

The attached patch allows the sysadmin to add a 'METRIC=n' to the interface's
/etc/sysconfig/network-scripts/ifcfg-foo file, to manually configure the
preference for the interface.

This functionality is already supported by 'ifup' for non-DHCP interfaces.
