Kaggle as datastore

[jlim262]

It'll be useful to have cloud services as datastore. Currently, Kaggle Dataset looks a good candidate to me. If a proper credential is provided, a dataset can be published with a version using 'create' command and be downloaded using 'download' as below. For the full description of the API, please refer to kaggle-api.
