IMPALA-4524: Batch ALTER TABLE...ADD PARTITION calls.

This commit allows users to add more than 500
(=MAX_PARTITION_UPDATES_PER_RPC) partitions in a single ALTER TABLE
command. We batch the operations against Hive into groups of 500.

I tested this manually, creating 1002 partitions and observing the
expected 3 API calls against the Hive Metastore in the log.  I can
confirm that there is coverage of this in some existing tests.  A new,
simple, test has been added that confirms that creating 502 partitions
works.
