IMPALA-10652: Optimize the checking of the size of incremental stats
Modify the estimation method of incremental statistics size:
incremental statistics size = Existing partition statistics
+ This time calculation partition stats
- Repeated calculation partition stats
Testing:
All partitions of a table have no incremental stats.
--Calculate the incremental stats of all partitions,
the incremental stats size exceeds the threshold,
an error is reported.
--Calculate the incremental stats of one partition,
no error is reported.
