Setup a docker compose file that creates an o11y stack for Spin to use

This is still a WIP, but I'd love feedback on the config itself and on where we want to store this config.

Can you give me some more context on how you imagine these being used? My gut is that this should be in a different repo, but without knowing about how this will be used, it's hard to say.

I envision some using this to easily setup an observability stack for their spin app

cd o11y
docker compose up
# Now do my Spin things

We could potentially put this in another repo, or hide it behind a spin plugin, or somewhere else. But, I do think we need to provide a simple and coherent story for how users of Spin can get the very wide set of o11y tools running easily.

Is this solving a Spin-specific observability issue or a "generic observability tools setup" issue? That might help guide the discussion.

I don't have a strong opinion about what repo this should live in, but if it's going to be in this repo I would like to put it in e.g. contrib/o11y-stack (or hack/..., as the k8s ecosystem seems to like) to indicate that it isn't an actively-supported feature of Spin itself.

As an aside I think tools/modsurfer should be moved for the same reason.

I like the pattern of hack/o11y-stack/*.

Good framing question @itowlson. There is nothing inherently specific to Spin here so I would say this is a "generic observability tools setup" issue.

I've moved it to hack/o11y-stack/. Looking for another round of reviews on if we're okay storing it there.

The great thing about hack/* is that we can just delete it later 🙂
