Cartesian support for aggregations

[craigtaverner]

There is absolutely no support for cartesian data in aggregations. Duplicating support from geographic data should be possible in most cases, except geohex which uses a model of the planet that is clearly only relevant to geographic data. The missing support for geo_shape in the distance aggregation is also something that could be implemented with similar intersection considerations as the grid aggregations.

The plan is to select one aggregation and complete it full stack, and from that evaluate the level of effort to complete all. First choice is centroid.
