Description of change

TODO: proper image tagging instead of relying on :latest

[dklimpel]

With #901 you can create images by pushing to master or by start job manually.

It creates images with latest or <md5_checksum_from_imagefile> tag. It is possible to add images when a tag in repo is set.

Then it would be possible, for example, to create a latest image (or <branch_name> or <md5_checksum_from_imagefile> in the pipeline if the checksum is not correct and otherwise use the image from a defined or checksum tag.
