Description Lili Cosic 2020-02-03 09:48:55 UTC 
Description of problem:
Initial dropping of deprecated metrics missed etcd, as they have moved their ServiceMonitor file in their operator repo.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Open Prometheus and search for any fo the following metrics:
etcd_(helper_cache_hit_count|helper_cache_miss_count|helper_cache_entry_count|request_cache_get_latencies_summary|request_cache_add_latencies_summary|request_latencies_summary)


Expected results:

We want to drop those metrics, so we should not see any when querying in Prometheus
