speed up integration with prometheus when is controlled by operators in Openshift

[lucky-sideburn]

Hi!

I create this project for the integration with Openmetrics/Prometheus.

To avoid to configure too many annotations and tls certs i created this Prometheus exporter for Openshift, used for collecting only a subset of important metrics. You can configure jobs or namespace as source of metrics (useful for take only node-exporter, openshift-state-metrics or etcd metrics). I used it for integrate Prometheus stack installed on Openshift 4.10 with Datadog without add annotations on exporters and containers across the cluster (usually controlled by operators)

I hope it will be useful for you ;)

Thanks,
Eug
