tests: Add basic integration testing

Add basic integration testing of the hypervisor using a cloud-init to
configure the VM at boot and SSH to control it at runtime.

Initial test just boots the VM up checks some basic resources and
reboots. With a second test that calls into the first to check that
subsequent tests work correctly.
