Product First/Last Seen Values Access

The recent introduction of the Product First Seen and Product Last Seen fields is great, but we are lacking the ability to see them on users and leverage them. 

Idea: Display the list of fields on the individual user view. Allowing us to see if a user has been active in multiple products and when they started/last visited each. 

Idea: Make the fields available in the API so that we can query and leverage the values.
