Test dib image builds with devstack too.

This adds a second nodepool label that the devstack plugin will attempt
to build and boot. For this image it will use DIB to build a very
minimal ubuntu VM that should accept ssh connections from nodepool.

Note it adds system deps for dib including debootstrap.
