Collection of utilities to allow exposing prometheus metrics from pekko-http endpoint using the prometheus java client

"com.varwise" %% "prometheus-pekko-http" % "2.0.0"

prometheus-akka-http - same thing but for akka-http

Version 2.0.0 uses Prometheus Java client library 1.0.0 which introduced some breaking changes.

Here's the quick migration guide:

1. Replace occurrences of io.prometheus.client.CollectorRegistry with io.prometheus.metrics.model.registry.PrometheusRegistry.
2. Supply ExecutionContext instance to MetricsEndpoint.
