I've been told, it's not.
You need explicitly to describe what you want the installer to do.

If you'd remove the collectd containers, you should get the cloud in a
usable state quickly, since that won't overwhelm gnocchi anymore.
Again, using traditional telemetry in such a large deployment is not a
good idea. Use ceph as gnocchi backend, if you really need gnocchi.
