Add linaro to cloud launcher

Following on from I166d9f669ea88663d4ffe70e25a6e908d11cf35f, add to
the cloud launcher.  For now just add keys and security (no special
network setup).

Add a default image to the control plane account, as the cloud
currently doesn't have a xenial-based image.  It needs a few special
properties to boot.
