we are running 2 prometheus replicas which means we are HA but cortex also allow to deReplicate which means when running 2 replicas ar erunning we can choose to only use one of 2 replicas and this is where consul is used
consul is only used for the HA
lets one promtheus to be scraped only when one of them is running
so for Common cluster it selects one of the replicas 8
