    Description

      Just like NFS we should write a heartbeat for each Instance to RADOS.

      Each hosts could write a simple object like: <pool>/<host ip>

      They simply write the timestamp to the object encoded in JSON.

      Other hosts can read that object and see if the host wrote the timestamp lately. If it did it means that it is still up and running and Fencing is not needed or required.
