Add cinder support
* using the new functional pattern: cinder_XXX functions are in
lib/cinder
* enable with 'c-api,c-sch,c-vol' in ENABLED_SERVICES, n-vol is still the default
* exercises/volumes.sh runs for cinder and n-vol
* move config to /etc/cinder
* change volume_group to stack-volumes; this also renames the backing file
to /opt/stack/data/stack-volumes-backing-file.
* removes osapi_volume from nova.conf enabled_apis
* integrates cinder + keystone
* launches c-sch
* tweaks for multi node
* move enabled_apis substitution to init_cinder
18Jun2010
* restored & rebased
* update setup.py to use setup_develop() in lib/cinder
