## About the changes
This PR improves our queries to Prometheus (instead of making multiple queries do only one) and improves the UI and the code.
The reports aggregate all HTTP methods (GET, POST, PUT, DELETE, OPTIONS, HEAD and PATCH) without distinction under the same "endpoint" (a relative path inside unleash up to a certain depth)
