Closes-Bug: #1399014
    Need simple Ceph pool info for OSDs in UI
Fix:
    adding a new property to each and every OSD’s list i.e.  ”ceph_crush_name”: “hdd” or “ssd” to summary default tree and added only to osd’s belong to ssd-root or hdd-root,  (for default-root osds which are not part of ssd/hdd root there will be no property).
    mapping for ceph crush name —> Pool Names
     hdd =  volumes_hdd, volumes, images
     ssd = volumes_ssd
     default= volumes, images
Test:
     checked with Summary tree with this new property for all OSD's
