repo: introduce enable_downloads and enable_statistics when creating repos These booleans were not shown in the normal repo creation form, so the form validation applied the "default" values of False. These values were however not used by the model when creating repos - it just unconditionally used the real global defaults. The API already exposed some of this, but it wasn't implemented. The web form for creating repos lacked these fields, but it was present in the repo edit form. Just make these fields mandatory. There will thus not be any defaults to apply in the model for creating repos.
