It allows us to already start testing pluggable object databases and the
object storage format extension together with a payload. But more
importantly it matches the semantics that we also have with the ref
storage format, where you can also configure the location.

We also have some use case for this at GitLab as a building block for
migrations. But the above two reasons are the more interesting ones for
now.

I'll adapt the commit message.
