Malformed /etc/network/interfaces generated when no gateway defined

[Chris Ricker]

Commenting out node_gateway in site.pp (as site.pp directs users to do when not needed) generates this stanza in /etc/network/interfaces:

iface eth2 inet static
netmask 255.255.255.0
address 2.3.1.2
dns-search sdu.lab
gateway
dns-nameservers 2.3.1.254

The gateway line causes various Debian components not to parse the file correctly -- the line should just be omitted entirely

This is also the source of these errors during puppet runs:

debug: Service[networking](provider=debian): Executing '/etc/init.d/networking start'
err: /Stage[main]/Control/Service[networking]/ensure: change from stopped to running failed: Could not start Service[networking]: Execution of '/etc/init.d/networking start' returned 1: at /etc/puppet/manifests/core.pp:302
