Should zabbix discovered hosts be subject to --interface-cidr filtering too?

[mikesilky]

In L373-385 of bin/zcollective we filter the hosts that mcollective has discovered to only include the ones which match the given options[:interface_cidr] if set.

For performance reasons, should we also be filtering the hosts that we get out of Zabbix if this is set and only deal with hosts in there that match the IP range? ie. we would skip L299-314 if it's out of the given range?
