API endpoint for importing a project export

The GitLab project export is useful for backing up individual projects and transferring projects between instances. An API is being added to allow exports to be automated. We should add a corresponding API for importing project exports.

Proposal

Extend POST /projects with support for creating a project from a project export

changed the description

@DouweM if the project is large (e.g. 5GB) upload via HTTP API isn't likely to be stable. Looking at the existing GitLab API documentation I can't seen any resources that already support resumable uploads.

added DEPRECATED_import label

@ayufan Have we run into issues with large uploads with CI artifacts?

removed DEPRECATED_import label

@DouweM We don't receive any reports, but we also limit on GitLab.com to 1GB.

@jramsay We don't support resumable uploads, in the API or the web app, and it doesn't look like there's a standardized way to do so in the first place. Do you think this will be an issue that TCP can't solve itself? In the customer's use case, the connection would be inside a managed network anyway, so maybe stability will be less of an issue?
