Description of problem:
As monitoring user I want to have an unbounded number of performance counters with labels in each Ceph daemon, so these labels allow us to identify and provide a context in the form of information fields for each performance counter.

What we really need are metrics which contain the information regarding pools and images in a label.

For that we need to create a common support for labeled performance counters available for any Ceph daemon


Actual results:
For example, metrics like ceph_rbd_mirror_snapshot_image_<pool-name>_<image name>_snapshots_time_sum are unusable due to them containing the names for the pool and snapshot in the metric name itself.

Expected results:
What we really need are metrics which contain the information regarding pools and images in a label.

ceph_rbd_mirror_snapshot_image_snapshots_time_sum{image: imageName, pool: poolName} = 0.1
