v3.6.0

Changed

• Deprecated grid_geohex_frequency, grid_geohash_frequency, and
  grid_geotile_frequency aggregations in favor of new centroid_geohash_grid_frequency,
  centroid_geohex_grid_frequency, and centroid_geotile_grid_frequency aggregations

Added

• Added geometry_geohash_grid_frequency and geometry_geotile_grid_frequency that
  aggregate over the geometry of each Item rather than the centroid. Note that the geohex aggregation geometry_geohex_grid_frequency is not implemented, as OpenSearch 2.11
  does not yet support geohex_grid aggregations over geo_shape fields.
