This switches the webapp's vault remote api setup from orangerie (unibo infra)
to vangogh (azure).
- vault: Remove orangerie vault setup (clean up no longer used setup)
Another extra in this diff from an old discussion with @olasd:
- base_lister: Consistently require only package's presence
- deposit: Consistently require only package's presence
As explained orally to @anlambert, i left the webapp's requirement to latest so
that he can still deploy himself.
