The OSD subops were replaced with replication ops (i.e., MSG_OSD_REPOP

places eight ops into the repop class -- MSG_OSD_REPOP,
MSG_OSD_REPOPREPLY, MSG_OSD_PG_UPDATE_LOG_MISSING,
MSG_OSD_PG_UPDATE_LOG_MISSING_REPLY, MSG_OSD_EC_WRITE,
MSG_OSD_EC_WRITE_REPLY, MSG_OSD_EC_READ, and MSG_OSD_EC_READ_REPLY.

This alo removes dupliated code related to op classes in
mClockOpClassQueue and mClockClientQueue and combines into
mClockOpClassSupport.

The three configuration options
osd_op_queue_mclock_osd_subop_{res,wgt,lim} have also been replaced
with osd_op_queue_mclock_osd_rep_op_{res,wgt,lim}.

This also removes OpQueueItem::OpQueueable::op_type_t::osd_subop since
