This patch should not introduce any changes in the existing ES behavior. Its only goal is to allow subsequent addition of various hashing algorithms, such as quadkey, pluscode, hex, ...

Implements `geotile_grid` aggregation This patch refactors previous implementation #30240 This code uses the same base classes as `geohash_grid` agg, but uses a different hashing algorithm to allow zoom consistency. Each grid bucket is aligned to Web Mercator tiles.

This PR has been superseded by #37842
This PR is based on #30320, which adds support for multiple hashing algorithms. This PR add support for the map aggregation based on a very common "tile" pattern - given a zoom level, hashes are computed in the same way as tile indexes (zoom/x/y).
Allows precision 0..29 - corresponding with the traditional map zoom levels. The key is returned as
"key": "10/768/512"-- same format as most tile services -zoom/x/y. To test manually, use grid doc example, and add"type":"quadkey".TODO
