Sets up a VM with hardcoded paths to multiple source trees.
Creates a script for use with VMWare or a Vagrantfile.
Uses a configuration file (in JSON format) that stores the paths to checked-out
copies of OpenStack projects on the host machine. If the path is None then
it lets devstack download them.
