> In HDDS-6312, Recon is regulated to retrieve a limited number of delta updates from OM, which eliminates the possibility of large delta updates causing OM's OOM.
> We did this control by setting the configuration of "recon.om.delta.update.limit" and "recon.om.delta.update.loop.limit", the default consume speed would be 2000*10 per 10 minutes, but we are not sure if we are consuming at an optimal speed.
> This ticket is to add a metric to record the lag between Recon and OM, which can help to set an appropriate value and prepare for other near real-time works on the Recon side.
