Add support for metrics #208

Closed dejanb closed 2 years ago

dejanb commented 2 years ago

Add metrics for cloud components based on Prometheus/Grafana. It works in combination with https://github.com/drogue-iot/drogue-cloud-helm-charts/pull/12

This PR adds basics for drogue cloud monitoring, by:

adding drogue-cloud-metrics chart and option to install it
instrumenting for now http and mqtt endpoint with basic metrics

There's a new docs page with some explanations: docs/modules/deployment/pages/monitoring.adoc which should help with testing the PR. Short term TODO item is to bump actix-web-prom version once the https://github.com/nlopes/actix-web-prom/pull/61 is merged.
