Expose workflow job metrics via new actions-metrics-server (#2057)

* Add workflow job metrics to Github webhook server * Fix handling of workflow_job.Conclusion * Make the prometheus metrics exporter for the workflow jobs a dedicated application * chart: Add support for deploying actions-metrics-server * A few improvements to make it easy to cover in E2E * chart: Add missing actionsmetrics.service.yaml * chart: Do not modify actionsMetricsServer.replicaCount * chart: Add documentation for actionsMetrics and actionsMetricsServer Co-authored-by: Colin Heathman <cheathman@benchsci.com>
