[CI] Upload CI metrics to DataDog

This PR tests integration of Datadog CI custom metrics. My goal is to take various useful statistics (like the duration of stage 1 build, stage 2 build, and test execution) that we already gather into `metrics.json` and upload them as [custom metrics](https://docs.datadoghq.com/continuous_integration/pipelines/custom_commands/) into Datadog, so that we can observe job duration on a more granular level.
