Create Open Telemetry docs

[DataBoyTX]

I copied this from Percy's wiki page, removing any internal references to servers, dev envs, etc.

I think we can rename the doc to telemetry.md instead of Open-Telemetry.

• i renamed to telemetry.md
• I made a quick pass on text

@aucahuasi :

1. I thought commands need to run via ./release ... to work the new services, not docker compsoe

2. Maybe we need to experiment & chat (so after this PR), but to turn on the local UIs, we should show how to setup Caddy for limiting access to admins, and pointers to how to look at logs vs metrics vs traces. Likely can enlist @dess890 for writing up the latter once we've got smooth?

fixed, merging
