Title:
  nova rbd driver features are hard-coded, it should be readable from
  ceph.conf

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  In nova rbd driver rbd features are hard-coded.

                  rbd.RBD().clone(src_client.ioctx,
                                       image.encode('utf-8'),
                                       snapshot.encode('utf-8'),
                                       dest_client.ioctx,
                                       dest_name,
                                       features=rbd.RBD_FEATURE_LAYERING)

  
  If We see above given code we are just using RBD_FEATURE_LAYERING directly.
  This restrict users to use only hard-coded RBD_FEATURE_LAYERING feature. 

  We should give a fix which should allow users to opt in to upcoming
  features that have not yet become default and users can specify
  features in ceph.conf and nova can read features information from
  ceph.conf.

  Fix should be something like :

  Rreading rbd_default_features from ceph.conf for rbd
  features configuration, falling back to layering if nothing is found.
