+++ This bug was initially created as a clone of Bug #2251055 +++

Current Metrics sent by the ceph-exporter don't include user or bucket on the metric name, for example:

ceph_rgw_op_del_obj_bytes{Bucket="bkt", instance="localhost:9926", instance_id="8000", job="radosgw"}
ceph_rgw_op_del_obj_bytes{User="anonymous", instance="localhost:9926", instance_id="8000", job="radosgw"}

This adds an extra dimension for Prometheus and Grafana to query and filter out the specific data, making it very complex and resource-expensive to configure Grafana dashboards.

The request is to modify the ceph-exporter so it constructs the metrics it sends out to Prometheus using the metric's key. In the future, they could be for anything else, like groups, accounts,etc.

Examples on what the final metric being sent to Prometheus should look like:

-- GLOBAL --
ceph_rgw_op_del_obj_bytes
ceph_rgw_op_del_obj_bytes{instance="localhost:9926", instance_id="8000", job="radosgw"}


-- Bucket operations --
ceph_rgw_op_del_bucket_obj_bytes

ceph_rgw_op_del_bucket_obj_bytes{Bucket="bkt", instance="localhost:9926", instance_id="8000", job="radosgw"}
ceph_rgw_op_del_bucket_obj_bytes{Bucket="bkt2", instance="localhost:9926", instance_id="8000", job="radosgw"}

-- User operations --
ceph_rgw_op_del_user_obj_bytes

ceph_rgw_op_del_user_obj_bytes{User="anonymous", instance="localhost:9926", instance_id="8000", job="radosgw"}
ceph_rgw_op_del_user_obj_bytes{User="test3", instance="localhost:9926", instance_id="8000", job="radosgw"}
