Doc Text:
.Setting ownership is faster when using `switch-from-non-containerized-to-containerized-ceph-daemons.yml` Previously, the `chown` command in the `switch-from-non-containerized-to-containerized-ceph-daemons.yml` playbook unconditionally re-applied the ownership of Ceph directories and files causing a lot of write operations. With this update, the command has been improved to run faster. This is especially useful on a {product} cluster with a significant amount of directories and files in the `/var/lib/ceph/` directory.

Description John Fulton 2019-10-01 12:15:12 UTC 
ceph-ansible v4 uses the ansible command module to directly run the chown command instead of using the ansible file module. This improves the speed of upgrades:

https://github.com/ceph/ceph-ansible/commit/47bf47c9d87fe057bc1402f7a1aa0a84d13b5fd0

Please backport this change to ceph-ansible 3.x.
