Zhihua Deng resolved HIVE-27746.
--------------------------------
    Fix Version/s: 4.1.0
       Resolution: Fixed

Merged to master. Thank you [~hemanth619] , [~jfs] and [~henrib] for the review!

A property: metastore.alterPartitions.notification.v2.enabled is introduced to ensure backward compatibility when it sets to false, so downstream notification consumers can still process the ALTER_PARTITION event without changes.

> In HIVE-3938, work was done to send single AddPartitionEvent for APIs that add partitions in bulk. Similarly, we have alter_partitions APIs that alter partitions in bulk via a single HMS call. For such events, we should also send a single AlterPartitionEvent with a list of partitions in it.
> This would be way more efficient than having to send and process them individually.
> This fix will be incompatible with the older clients that expect single partition.
