Dataset upload feature (master ticket)

[wwaites]

• Upload - ​http://ckan.okfnpad.org/storage
  • Create a package -> add a resource -> Oh, i haven't uploaded yet, 'upload here' ...
  • ckan.net/upload/ -> standard upload form
    • OFS + boto -> generate form key (and create the bucket if it doesn't exist? Or do we assume bucket already exists)
    • ckan.net/api/utils/
  • We want CKAN extension

2 (4) use cases: (With and without access to auth keys.)

• upload form on ckan.ne (by default with key)
• datapkg upload (client) (by default without key) (plumbing done)

1. Upload form on ckan.net (with access to keys)
2. API for getting credentials for upload from ckan.net api (deprecate storage.ckan.net)
