Clark Boylan f490260de7 Add support to launch node for attaching volumes
We are using cinder block devices more and more. Update launch node so
that it can attach a preexisting cinder volume against a new nova server
on first boot. This will allow puppet or other config management to
format and mount that block device into the VMs filesystem.

# Sigh. nova volume-attach is not immediate, but there is no status to track
