Reviewers: JIRA

Add exchange partition to hive

This diff adds an exchange partition feature to hive. The command is of the following format:
ALTER TABLE <source_table_name> EXCHANGE PARTITION <partition> WITH TABLE <dest_table_name>
This only works if <source_table_name> and <dest_table_name> have the same field
schemas and the same partition by parameters. If they do no the command will throw an exception.
This will take the partition from <partition> from <source_table_name> and will
do an HDFS rename of the partition folder so that the partition now belongs to <dest_table_name>.
It will also change the metadata to show that partition of <source_table_name> has been
deleted and added to <dest_table_name>.
