Cloud Native deployment umbrella issue

[martin-helmich]

As discussed earlier today in #209 (comment), I'm creating this issue as an umbrella issue for offering a better cloud-native experience.

• Helm Chart for easy Kubernetes deployment #209 (also see its sister issue Create chart for TYPO3 christianhuth/helm-charts#17)
• Support for automatic installation and configuration via environment variables #230
• Redis support #231
• Build more compact images #232
• Add support for liveness and readiness probes #233
• Provide Docker images with exact version numbers #234

I'll welcome any additions to this list. To prevent clutter, I kindly ask to keep discussions within the respective sub-issues. 🙂

Maybe there should also be support for having Dockerimages according to SemVer? At the moment you only publish images for 10.4, 11.5 and so on, but not for 10.4.31, 10.4.32, ...
