we already have prometheus_client (which is push-style), not sure why we need +1 similar metrics client

Hi @AskAlexSharov . Pyroscope is used for profiling data collection so its additional data not exactly the same as Prometheus metrics. Also, this is something that is planned to be added to the https://github.com/NethermindEth/gas-benchmarks which would provide more data for finding out bottlenecks on the scenarios there.
