Arvp VM tools

At arvp, we need to a fast and frictionless way for new members to get started with our software stack. Asking them to install it on their own devices has failed in the past. To resolve this, we'd like to create separate VMs on our main server for new members. The machines will automatically create themselves, when the arvp member logs in. They'll have the basics setup in an isolated environment, allowing for members to experiment without fear.

Our initial design intent is a mix of sshd's ForceCommand and qemu!
