+- More accurate memory estimations while building an on-heap incremental
index. Rather than using the max possible size of an aggregated row, Druid can
now use (based on a task context flag) a closer estimate of the actual heap
footprint of an aggregated row. This enables the indexer to fit more rows in
memory before doing an intermediate persist.
