Enable to manage "INDEX / NOINDEX" properties for design studio hosted documents

As noted almost 3 years ago, if documents are stored in the design studio and referenced with a link from an indexable LP, it is likely they will be indexed as well. See Are documents hosted in Marketo searchable via Google or other search engines?

It would be better if we had the option to protect these docs from indexing. When loading a doc, we would have the option to make in INDEX or NOINDEX. The default would be NOINDEX

This would generate the appropriate robot.txt.

Alternatively, this would be done globally per document type in the admin
