task/buildah/0.10/buildah.yaml: add feature to allow pushing additional tags
This feature allows specifying additional tags like the commit hash or the date or similar, that will be used in addition to "latest".
Please note, those tags need to be strings, not commands like $(date +%Y%m%d).

I have tested this locally and will look into the checklist to see, what I missed.

Discussion see #1373

ADDITIONAL_TAGS param is missing isn't it ?

You are right, I forgot. I just pushed a commit with the README changes.
