`BaseUploader` is now the base class for `FileUploader`,
`JobArtifactUploader` and `LfsUploader`

`BaseDownloader` is now the base class for `FileDownloader`,
`JobArtifactDownloader`, and `LfsDownloader`

Git doesn't track file moves correctly so we have to split the operation
 in two different commits.

Every class related to blob replication will live in
`Gitlab::Geo::Replication`

Use less meta-programming to make it easy to refactor the codebase.

Gitlab::Geo::FileReplication should hold logic that is shared among
multiple classes.
