coordination #80150

Updated by okurz over 1 year ago

## Motivation
Nowadays a container based deployment becomes industry standard which we should fully support and prominently feature as supported for simple single-instance setups of individual persons

## Acceptance criteria
* **AC1:** documentation exists for simple single-instance setups, e.g. "get your openQA tests to run in less than 5 minutes"
* **AC2:** not more than a couple of shell script lines, at best 1 line
* **AC3:** The documentation suggests a single way for newcomers, not overwhelms with too many alternatives in parallel
