Code Issues Proposed changes

Enable VM DHCP request to reach DHCP agent

Browse Source 
When using the firewall driver IptablesFirewallDriver and the
default INPUT and FORWARD rules are DISCARD then the DHCP
request from the VM is discarded prior to getting to the dnsmasq.

A new rule will be added that enables DHCP requests to pass.

This fixes bug 1131223
