[wecharyu]

What changes were proposed in this pull request?

Introduce a new SQL to enable unset SERDE properties:

ALTER TABLE table_identifier partition_spec UNSET SERDEPROPERTIES [ IF EXISTS ] ( key1, key2, ... )

Why are the changes needed?

Spark SQL already supports SET SERDEPROPERTIES, it would be more convenient if we can use UNSET SERDEPROPETIES

Yes, user can use this new SQL.
