In Discover, be able to show doc_values for any field not stored

[micoq]

Currently in Discover, you can only view or select stored fields (in _source or stored separately with "store":true)

It might also be useful to be able to display the doc_values for some fields when you don't want to store them. Especially for:

• high cardinality numeric values
• low cardinality keywords already used in aggregations

For a limited number of fields, the seek load on doc values remains limited and you can save some precious percents on your storage.

Closing this because it's not planned to be resolved in the foreseeable future. It will be tracked in our Icebox and will be re-opened if our priorities change. Feel free to re-open if you think it should be melted sooner.
