virt: Add more flexible way to specify comm ports host -> guest
When running the virt guest windows tests using the (now default)
autotest private bridge, noticed that some ports needed for host
and guest communication weren't specified. So, add a config file
knob to allow people to specify additional ports to be added to
the default firewall configuration. The config tracks some important
ports used on tests, such as the remote shell ports and remote
shell file transfer ports.
