[Pacemaker] Why CIB is client of CCM?

Hi Beekhof & Lars,

I found actually both Pacemaker CRMD and CIB are all clients of Heartbeat
CCM.  And I think CRMD would update the crm_node information once ccm
membership status change which reflect to CIB update eventually.

Why CIB register itself as client still? Seems what cib_ccm_msg_callback()
does same thing as crmd_ccm_msg_callback()->do_ccm_update_cache().
Do I miss anything? Looking forward to your guidance.

Thanks
