Add a new dataset-level checkbox option for "Non-commercial use only" #449
Description
A new bit of metadata to store for each dataset. Could be placed near these options:
A checkbox that says "Non-commercial use only" next to it.
This flag will be be used later when displaying a data request to reviewers to indicate/flag that the request contains 1 or more "Non-commercial use only" datasets, which should add a layer of protection against a principal reviewer inadvertently approving a commercial user/entity's request for a non-commercial use only dataset.
