Doc: Update Kolla Ceph document for mixed Ceph OSD deployment 

Since Rocky release Kolla Ceph supports both bluestore and
filestore Ceph OSD. In multinode mode, users can overwrite
“ceph_osd_store_type” in the inventory file and deploy the mixed
Ceph OSD.

.. note::
Kolla Ceph supports mixed Ceph OSD deployment, i.e. some Ceph OSDs are
bluestore, the others are filestore. The ``ceph_osd_store_type`` of each
Ceph OSD can be configured under ``[storage]`` in the multinode inventory
file. The Ceph OSD store type is unique in one storage node. For example:
.. code-block:: ini
[storage]
storage_node1_hostname ceph_osd_store_type=bluestore
storage_node2_hostname ceph_osd_store_type=bluestore
storage_node3_hostname ceph_osd_store_type=filestore
storage_node4_hostname ceph_osd_store_type=filestore
