Check tag
The goal is to add a "check tag" step which is performed before installation on the lab or TN. This is a cousin MR to e3/e3!43 (merged).
Testing has been performed here:
- https://gitlab.esss.lu.se/e3/common/e3-auth/-/pipelines/70875 - deploy fails, tag wrong format
- https://gitlab.esss.lu.se/e3/common/e3-auth/-/pipelines/70877 - deploy fails, tag correct format but wrong data
- https://gitlab.esss.lu.se/e3/common/e3-auth/-/pipelines/70881 - "deploy" passes, tag correct
