docs: start doc for distributed tracing and logs guidance

[cijothomas]

WIP. We already have some docs for metrics, this is adding mostly placeholder for logs, and some guidance into traces. Not intended to be running examples, but more like setting direction on how to instrument. This is usually not required in OTel repos (as OTel is the obvious API), but we need to cover this to help users navigate the existing ecosystem around tracing.
