Message interpolation

[whatyouhide]

Messages support interpolation:

{
  "message": {
    "message": "My raw message with interpreted strings like %s",
    "params": ["this"]
  }
}

I assume this is used to easily group messages regardless of the values being interpolated. If so, I think we should support this in the Sentry.capture_message/1 function. A couple of proposed APIs:

# Option #1: with a tuple
Sentry.capture_message({"Interpolated %s", ["message"]}, options)

# Option #2: through options
Sentry.capture_message("Interpolated %s", formatting_parameters: ["message"])

yes indeed, we do this in python in our logging integration but we don't expose the params in capture_message yet, but we should.

I like option 2 a bit more, because it makes the optionality explicit.
