I hope this will fix the Geo failure.

`ObjectStorage::Concern` adds delegation to the model that
mount an uploader that uses `RecordsUploads::Concern` to track
its uploads. The basic implementation is to use the uploader
to build paths that can be used to fetch back the related `Upload`
instance so it can be used to build the uploader back (which is
needed to build the correct file URL).

I've demoted the ObjectStoreUploader to a concern that is mixed in
the concrete uploader classes that need to store files in a remote
object store.

I've been working on making the local -> remote migration working
first, which has been trivial compared to the remote -> local one.

The current implementation is heavily based on side-effects which
makes the code brittle and hard to reason about.

The current approach is to store the `store` field in the correct
`Upload` model once a migration has been done. To retrieve the field
I use the `has_many :uploads` relationship, with all the paths that
a certain file may have `uploads.where(path: paths).last`. This as
the drawback of adding a database query for every upload lookup, but
I feel that the generalization of this behavior is worth it. We should
be able to optimize this down the road quite easily.

When a postgresql replication slot is not active, one should not just delete it.
Instead ask themselves, should it be active and if so, why isn't it active.

If they intent to not use it, they can remove it.
