This backports to CE changes that allow the recording of the
repository_type in the table lfs_objects_projects.
This is in order to allow future pruning of unreferenced LFS objects,
as we will need to know which repository to look in for the LFS pointer
file.
The EE MR that contains the original code and a full explanation of the
changes is
https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/13894
EE Issue https://gitlab.com/gitlab-org/gitlab-ee/issues/9490
Note that there was a lot of CE code changed in the EE MR because we
want to allow the wiki repository to also use LFS. See
https://gitlab.com/gitlab-org/gitlab-ce/issues/43721. As the wiki is
an unlicensed feature, a full backport is required to enable this.
Updates Files::MultiService for the commits API which is in turn used by the
multi-file upload web UI
Ensures that files which should be in LFS are transformed into LFS pointers
Uses Lfs::Transformer which then links LfsObjectProjects on success
Uses Lfs::FileModificationHandler to coordinate LFS detection, creation of LfsObject, etc
Caveats:
1. This isn't used by the multi-file editor / Web IDE
2. This isn't used on rename. We'd need to be able to download LFS files
and add them to the commit if they no longer match so not as simple.
3. We only check the root .gitattributes file, so this should be improved
to correctly check for nested .gitattributes files in subfolders.
