Clark Boylan 6429922e99 Add support to launch-node for cinder attach
Now that we have a shade version of the launch node script adding in
support for attaching a cinder volume is simple. Do this so that
launching mirrors which rely on cinder volumes is simpler.

This updates the mount_volume.sh script to setup the first cinder volume
with lvm and mount it under the specified path. It will also install
lvm2 pacakges since they may not be present on all base images.

This updates the make_swap.sh script to avoid blindly using /dev/vdb as
the location for swap as this may be a cinder volume or config drive.

We add availability zone, device specification, mount path, and
fs label support to shade-launch-node.py as these are all necessary
inputs to properly mount a cinder volume in a VM.
