Flesh cinder install section

The cinder install section previously only had package install

It splits out controller sections from a block storage node
where the disk lives.

this patch adds database, endpoint creation, service restarts.

what's needed: block1: creation of volume group, tgt setup
(suggest following http://devstack.org/lib/cinder.html)

both: setting driver and key manager

as usual, if fifieldt is not on IRC this patch is up for grabs
