Thanks; this is just a new unit test so I don't think it needs senior maintainer approval. |

…xy#27239) Commit Message: Reproduces a scenario where it's difficult to use a streaming optimization for Prometheus stats based on scopes without introducing a bug. Context: Issue that /stats/prometheus endpoint takes too much much memory: Prometheus stats handler used too much memory. envoyproxy#16139 Solution for non-Prometheus endpoints to use less memory for /stats and run faster: admin: Streaming /stats implementation envoyproxy#19693 which I believe is working well. This solution mapped to Prometheus: Prom stats perf improvements envoyproxy#24998 A case where this solution has a duplicate# TYPE line due to two stats with the same tag-extracted-stat name from two different scopes: stats: prometheus scrape failed envoyproxy#27173 Note that the existing unit tests did not exercise that scenario so this PR adds a testcase.
