Create docker-compose.yml to run different test flavors

[konradkonrad]

Currently we run the continuous tests like this:

docker run --name continuous-test -d --env-file .env --network keyper-metrics_default -v $(pwd)/data/blame:/blame -v $(pwd)/data/config:/config continuous-testing continuous

The stress tests on the other hand, are run from a go test invocation (with settings in stress/.envrc).

It would be much better to integrate the different test runners in a docker-compose.yml, where one can execute a certain test with a known command, e.g.:

• docker compose scale continuous=1 OR
• docker compose --profile=continuous up OR
• docker compose run continuous

depending on which of the above is a good solution for us.
