vmware-vmx clarify VMware Fusion support
Force IPv4 addresses from address pools in Openstack. Fixes #1258

Rackspace defaults to a public IPv4 and IPv6 address. These are returned in
random order, with the sprintf further on generating an incorrect connection
string if on IPv6. Force IPv4 until support for correct connection strings and
a configuration flag for logging in over IPv6 is added.
Add ability to configure networks for openstack

Add configuration option `networks`, a list of network UUIDs, to attach to the
source instance.

In some openstack installs, no default network will be attached or the network
with the ability to attach a public floating IP will need to be specified.
