Thanks for this @Fedosin 👍

Some initial comments. I also think we need to remove all the hack/observability stuff from this and upstream this to CAPI so that otel becomes an option in the observability part of the Tiltfile.

@Fedosin this looks good to me, thanks for this. Would you be able to squash your commits?

@richardcase Give me a couple of more days. I'm going to add more injections.
