Feature: automatic tagging
We add a stage to the CI/CD pipeline to post automatically a tag, which is then immediately removed.
This tag is used by LHC Impedance Docker Image to automatically update the docker image every time that a commit is pushed to IW2D. This way the image is always up to date.
The tag is removed right after it is created, so that we don't keep unwanted tags.
