Fix the recommendation about file system of Ceph

Browse Source 
The current document mentions that ceph developers recommend btrfs as a
fs for storage, however this is not the case as btrfs is not yet stable
for production clusters and only recommended in not critical
environments.

<para>Ceph developers recommend that you use <systemitem>Btrfs</systemitem> as a file system
for storage. XFS might be a better alternative for production environments;XFS
is an excellent alternative to Btrfs. The ext4 file system is also compatible but does
not exploit the power of Ceph.</para>
<para>Ceph developers recommend XFS for production deployments, <systemitem>Btrfs</systemitem>
for testing, development, and any non-critical deployments. Btrfs has the correct
feature set and roadmap to serve Ceph in the long-term, but XFS and ext4 provide the
necessary stability for today’s deployments.</para>
<note>
<para>If using <systemitem>Btrfs</systemitem>, ensure that you use the correct version
