Add dynamic config compatibility

- Use APCu cache as default caching mechanism
- Add explicit redis environment variables for redis lock-support
- Add a lot of environment variables, which aren't part of admin-page
- Add possibility to disable URL & E-Mail validation (for demo-page)
- Dynamically copy /config/ content without overwriting existing one

Add opcache support for performance reason
Add multi-core support for php extensions install

Bump redis version to 5.0.1 (last stable)

Exclude /log/ directory during sync (to avoid deleting logs)
