continue PR: " docs: improve documentation around gathering telemetry"

[ppcano]

This PR continues #33. I wait for a decision whether it should be merged into the same branch/PR.

(1) - For easier docker setup, this PR adds docker-compose files: docker-compose-local.yaml and docker-compose-cloud.yaml

(2) - Updated readme instructions

(3) - Could not setup Loki (see error on this diff). We can try i the Loki integration in a following PR.

(4) - Next, on another PR, I want to include a case to send k6 metrics to Prometheus and visualize with the pre-built dashboards.

I have tested both docker compose setups and they work well. PR seems ready - adding also @dgzlopes for review.

The issue regarding the autoconfigure module is probably caused by token permissions. The token needs the stacks:read scope. It sounds like this is missing. We'll have to decide if we want to put the extra burden on token creation or have the user collect all the relevant infos ({prom,loki,tempo,pyroscope} url, tenant) themselves

@theSuess - Yep, that was, thank you! I added a minor comment.

I got confused because I could not find the GET stack API documentation. Should I open an issue?
