[EPIC] META CLI for Docker & Docker Compose Maintenance

• Provide a simple META CLI for deploying & maintaining Docker & Docker Compose images. It should be located in the meta repository.
• Elegantly integrate with app config files and environment variables with Docker. Hence such concept needs to be available beforehand.
• Flexible argument parsing.
• Check if knowledge or code from the existing "Aura Web" Docker Compose POC can be re-used (see https://gitlab.servus.at/aura/aura-web).

Specification

Specification and documentation shall be provided before implementation: https://gitlab.servus.at/aura/meta/-/blob/master/docs/development/cli.md

TODO

The required CLI features are two-fold:

1. SysOps Commands

• It shall work independent from other repositories. The ready-build images shall be drawn from dockerhub.com.
• Simple approach (one-liner) to run a single docker container, for example $meta ./run.sh docker:steering. Details on settings need to be documented here: https://gitlab.servus.at/aura/meta/-/blob/master/docs/administration/install-docker.md and here
• Simple approach (one-liner) to run the two Docker Compose "Aura Web" and "Aura Playout". Needs to be documented here: https://gitlab.servus.at/aura/meta/-/blob/master/docs/administration/install-docker-compose.md

2. Release Management Commands

• Simple commands to tag, push, release a defined software version
• Synchronization of versions in code/configs (for example npm packages), git tags and dockerhub tags
• Optional: Integration with Gitlab Milestones, Version pages and CI/CD

OPTIONAL TASK: #45 [EPIC ] Advanced CLI - Replace the existing run.sh scripts with some proven CLI Framework
