gitlab-ci: Accept $BUILD_ID CI var to create additional tags
When triggering a pipeline, by setting the BUILD_ID CI variable it is
now possible to tell the pipeline to create $IMAGE:$BUILD_ID tags
like v2022dev0-image-builder:20201225.000.
With this it is possible to have an external orchestrator trigger all the nightly pipelines with a shared build id, rather than have each pipeline compute one at different times.
