Enhancements, see details

- Added a message to explain to the user that it needs to build and push
  images
- The Release Name string is now a constant ins source code, later we will be able to
  change it to (for example) a template call
- SHA256 injected label (from docker-compose file content) is a bit long, SHA1 is shorter
- We now add compose command line and generation date in the Values file
- Code cleanup, refactorisation and enhancements
- More documentation in the source code
