Support for geohash_grid in composite aggs

[benwtrent]

geohash_grid seems like a natural fit for a composite agg source. Being able to iterate over geo buckets could open up some interesting use cases.

Is this enhancement already implemented? Thanks!!

[benwtrent]

@henargv not yet. I personally have not had any cycles yet to take a stab at it.

I am not 100% sure if it will be straight forward or not, but the current composite aggs in org.elasticsearch.search.aggregations.bucket.composite provide good examples of how this needs to be implemented.

@benwtrent I believe this can be closed, correct?

[benwtrent]

I think so. geotile_grid covers it :)
