Review request for hive, Alexander Kolbasov and Vihang Karajgaonkar.
Bugs: HIVE-19718
https://issues.apache.org/jira/browse/HIVE-19718
Repository: hive-git
Description
-------
Various optimization for addPartitions call:
- Push down table object to convertToMPart
- Push down partitionKeys to startAddPartition -> doesPartitionExist ->
getMPartition, so it does not have to query the table object for every time if
we add multiple partitions for the same table
- The original getMPartition used to query the table every time. Created a new
version of getMPartition, which can use the provided partitionKeys instead of
querying it again.

Testing
-------
Run several performance tests with Sasha's performance tool. These
optimisations shave of ~10% of the runtime
Thanks,
