> As part of PHOENIX-3822, we surfaced byte and row estimates for queries in explain plan.
Since we collect this information through stats collection, it would also be helpful to surface
when this information was last updated to reflect its freshness. We already store last_stats_update_time
in SYSTEM.STATS. So the task would be essentially surfacing last_stats_update_time as another
column in the explain plan result set.
