02f386be33 Regard the GridCluster reduction strategy as private 
The *strategy* parameteriation will be considered an
implementation detail for the time being.

4580c9cd5c Change the cartodb_ids of aggregated overviews 
Instead of arbitrary ids, the id of one of the aggregated records
is used, so that if it is used in the UI to query point
the information of one of the records grouped at the point will be
retrieved.

6a6a5bc96a Fix Sampling reduction to avoid RandomTids problems 
The fixed cases will not be common but do occur in tests.
This is an interim fix which should be reverted if CDB_randomTids changes.

564ab75d2d Use _cdb_estimated_extent instead of ST_Extent 
With a 3.8M points table, this was a ~30% gain in my local env.

f7857945c1 Change feature density computation algorithm 
Now parameterize by the number of levels to traverse and
start with the level that covers the extent of the table
with at least N*N tiles (N=4).

554464e43e Use tile-recursive computation of feature density 
This is a more adaptive way of estimating the feature density to
determine the base Z level.
