The rbd_default_features extra configs parameter was removed from
this module as per I3242cfe0f141fe2bbb951ce2cf7071fd07456db8 so that,
as per I95cafec9160f5c3b1610a0408f2f80d567fcaa89, puppet-ceph could
manage it instead. This change passes the new rbd_default_features
parameter to puppet-ceph with a value of 15, the same value that this
module used to use for performance reasons.
