Currently, not all the central agent pollsters use discoveries. In order to enable horizontal scaling, all pollsters must use discoveries so the resources can be partitioned across the pool of running central agents. For pollsters that don't poll specific resources, but only poll general info from services, we treat the service endpoints as resources. So in the case of Glance, there will be only one resource available for all the pollsters (a Glance endpoint). If there are multiple agents running, only one will be assigned that endpoint and only one will poll Glance API.
