The debian packages for individual cinder services provide service
configs which automatically start after install, leading to all cinder
services running on each cinder volume host. Instead only install the
python3-cinder library package and rely on the service files OSA manages.
uwsgi packages are only required on hosts running cinder-api, so an
additional variable, 'cinder_api_distro_packages' has been added for
packages specific to those hosts.
Beginning in the Stein release, Ubuntu distro packages are now using
Python3. This requires additionally installing and using the uwsgi
python3 plugin.
