* Fixes hard-coded db password for Cinder with lookup
of the cinder_db_chef_role attribute
* Fixes typo of glance_host and glance_port in config template
* Fixes incorrect keystoneclient.middleware reference in api-paste
template
* Removes recipes/common.rb, as it was pointless now that the
config template processing had to be moved into each service recipe
* Removes the recipes/setup.rb, as it was all for the API service,
so moved the keystone_register calls directly into the api.rb recipe
