Adding an AlertManager Gmail Receiver

In a previous post, we added a PrometheusRule for Argo that caused an alert to fire when an Argo Workflow failed. We were able to see the alert fire in AlertManager. AlertManager is another component of Prometheus responsible for sending notifications for when an alert is firing.
