I'd like you to reexamine a change. Please visit

Change subject: IMPALA-10113: Add feature flag for incremental metadata updates

IMPALA-10113: Add feature flag for incremental metadata updates
This patch adds a feature flag, enable_incremental_metadata_updates, to
turn off incremental metadata (i.e. partition level metadata)
propagation from catalogd to coordinators. It defaults to true. When
setting to false, catalogd will send metadata updates in table
granularity (the legacy behavior).
Also fixes a bug of logging an empty aggregated partition update log
when no partitions are changed in a DDL.
Tests:
- Run CORE tests with this flag set to true and false.
- Add tests with enable_incremental_metadata_updates=false.
