Doc Text:
.Small objects and files in RADOS no longer use more space than required The Ceph Object Gateway and the Ceph file system (CephFS) stores small objects and files as individual objects in RADOS. Previously, objects smaller than BlueStore's default minimum allocation size (`min_alloc_size`) used more space than required. This happened because the earlier default value of BlueStore's `min_alloc_size` was 16 KB for solid state devices (SSDs) and 64 KB for (HDDs). Currently, the default value of `min_alloc_size` for SSDs and HDDs is 4 KB. This enables better use of space with no impact on performance.

In the provided doc noticed that the configurations are setting using ansible-playbook and this is not supported in ceph 5.0. Created a bug for the same.
Hence assigning the bug again.
