Openspending-compatible upload finalization api.

[Fak3]

To merge with os-conductor we should try to be compatible in the finalize upload API.

• Change url to /api/package/upload

• Request body should be json object in the format: {'datapackage': 'url'}

  • 'datapackage' should be url of the datapackage.json that was previously uploaded by the client on the BitStore
    • That url should be used in the controller code to fetch metadata and as base to fetch README contents.

• Currently we return 'status': 'OK', on success, but we should return 'status': 'queued' instead. (In the future we will have async job starting on the request. Right now it is not a priority. So no change for now)

Hm... I actually think that the 'status' should be better renamed to 'job_status', to clearly separate request status (as in http terms) and job status. We already use 'status': 'OK' everywhere in the API to indicate that the request handled successfully. But here the client may want to know both - job status (queued) and request status. So the proposal would be: on success: {status: ok, job_status: queued}
