Prometheus supports a lot in the HTTP scraping space, including oauth and Bearer token based scrape targets.

Currently we use Grafana cloud that has a list of IP address that can scrape from. This "can" change, and if it does and we hardcode this access into Atlas based on IP then it will break the scrape.

Could Mongo add support for token/oauth based scraping. Where we provide these tokens in a HTTPS call?

I think this would solve the issues with things like private link, or peered network connections. It would also allow "any" prometheus server that can make outbound HTTPS to scrape Atlas.
