Include LFS operation when requesting auth
To support https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/8044, we need to send through the LFS operation (either download
or upload
) when making the authentication request to the API.
In a Geo context, we want download
operations to come from a secondary but upload
operations to be sent to the primary.
