Review request for Siying Dong.


Changes
-------

Refactor the code, rename_partition shares the same thrift API as alter_partition, we do alter_partition
when part_vals is empty, we do rename_partition when part_vals is given 


Summary
-------

Implement ALTER TABLE PARTITION RENAME function to rename a partition. 
Add HiveQL syntax "ALTER TABLE bar PARTITION (k1='v1', k2='v2') RENAME TO PARTITION (k1='v3',
k2='v4');"
This is my first Hive diff, I just learn everything from existing codebase and may not have
a good understanding on it. 
Feel free to inform me if I make something wrong. Thanks

Testing
-------

Add a partition A in the table
Rename partition A to partition B
Show the partitions in the table, it returns partition B.
SELECT the data from partition A, it returns no results
SELECT the data from partition B, it returns the data originally stored in partition A


Thanks,
