HTTP polling - gRPC and HTTP/2

So the ingress controller is not exactly relevant to SW, that's a part of the cluster building thats going to happen where your thanos lives (im kind of assuming its a k8s deployment somewhere), essentially the ingress controller is their load balancer.  Since http2 is backward compatible and mostly the same as http1.1 that's not going to be a blocker for you, the changes are all in optimizing how connections are established but if you made a request with 1.1 you'd still get a response, it just does it in the classic serial pattern instead of being able to multiplex many requests and responses at once.

So focusing on the part that is specific to Orion, I've seen people attempt to use the SAM API monitor to scrape prom data, but the result is the full contents of the /metrics page and I don't think they've added a way for the API component to parse that into separate metrics yet.  So that basically leaves you needing to use a custom script component to do do an invoke-restmethod to get the contents of the page and then break it apart into the various metrics and format those into a response that Orion will like.

Thank you!  That's just the information needed.
