 - `prometheus_rules`: a list of custom prometheus rules based on [Prometheus 2.0 documentation](https://prometheus.io/docs/prometheus/latest/configuration/template_examples/), to create for this client. Please note to use `!unsafe` keyword as prefix for every string that uses dollar sign `$` to avoid templating. By default, `prometheus_rules` is empty and [standard rules](https://github.com/scalair/tethys/blob/dev/templates/prometheus/client.rules.j2) will be automatically applied for each defined `products`.
