.read_host_visible_ip_address(machine) ⇒ Object

!!!!!!!!!!!! !! NOTE !! !!!!!!!!!!!!

This is a fragile heuristic: we are simply assuming the IP address of the last interface non-localhost IP address is the host-visible one.

For VMWare, the interface that Vagrant uses is host accessible, so we expect this to be the same as ‘read_ip_address`.

For VirtualBox, the Vagrant interface is not host visible, so we add our own private_network, which we expect this to return for us.

If the Vagrantfile sets up any sort of fancy networking, this has the potential to fail, which will break things.

TODO: Find a better heuristic for this implementation.
