[Trino] ServiceMonitor additonal options

[metalshanked]

Currently the service monitor section exposes a few options.

Would be great if additional configuration can be allowed such as "port", "basic auth" etc

For example, here is a custom ServiceMonitor config to rewire it to use OpenMetrics from the trino instance.
Unfortunately, this would get overwritten by Trino Helm chart with servicemonitor as "true" in the chart
