Ceph support the option '--osd-crush-initial-weight' upon OSD start, which sets an explicit weight (in TiB units) to specific OSD. Allow passing this option all the way from the user (similar to 'DeviceClass'), for the special case where end users wants it cluster to have non-even balance over specific OSDs (e.g., one of the OSDs is placed over a partition alongside OS-partition).
