Is it possible to whitelist libraries in painless (like GeoUtils)?

Hi mike,

I've moved this to the elasticsearch forum since (at least from my initial search) this is looking like a limitation at that level.

If there's some known way to configure ES to allow it I can help figure out if it's possible in a cloud instance.

At this point painless's whitelist is not configurable or pluggable in any  
way. At some point it'll be more flexible but we're weary to make it super  
flexible because adding bad things could lead to security issues.
