chore(docker): add gcloud storage to docker container

[project-defiant]

✨ Context

Harmoniation and QC steps are using the docker container defined in orchestration. The container wraps gentropy container and adds two things on top:

1. Google Cloud SDK
2. script to perform two steps simuntanously

Later the container is build via github actions from orchestration tag.

The approach described above no longer holds, as of migration to the pipeline repository we no longer can support tags specific to orchestration@harmonisation. This is due to the fact that the repository now needs to host tags for PTS, PIS, croissant and orchestration. To prevent additional complexity we decided to remove the harmonisation container from orchestration. This can be done, as the orchestration google batch jobs now support putting inline scripts to run through the batch tasks, which simplify the harmonisation as we can use gentropy image directly.
