Updates cinder element

The previous cinder element was lacking a notty file and didn't
open the required ports in iptables.  This patch also allows a
developer to install the minimum required components for a
single cinder instance or (n) cinder-volume nodes.

This update results in 3 elements
cinder        : common cinder element
cinder-api    : installs the cinder api and scheduler
cinder-volume : installs the cinder volume service

Updates gearman iptables file

Once we move to a readonly root filesystem we cannot store
the .ok file in the git tree.

Updates nova notty file

No need for appending to the notty file, standard redirect of
output is more appropriate.
