Review Comment:
Thanks @saihemanth-cloudera for the comment. Introduce `List<Partition>
dropPartitions(DropPartitionsRequest req, PartitionDropOptions options)`
instead, support HMS deleting partitions in batch by the provided partition
names.

> When large number of tables and dbs are present, it takes lot of time to
> iterate over all tables in PartitionManagementTask.
> If table parameters are populated in TableMeta, it will cut down lots of
> interactions with HMS in PartitionManagementTask.
