Add support for various charsets in LazySimpleSerDe
---------------------------------------------------

                 Key: HIVE-2917
                 URL: https://issues.apache.org/jira/browse/HIVE-2917
             Project: Hive
          Issue Type: New Feature
          Components: CLI, Serializers/Deserializers
    Affects Versions: 0.9.0
            Reporter: Kai Zhang


Currently hive can only serialize/deserialize data encoded in utf-8.

It would be useful to specify the data's charset when creating the table.

The idea is to add a new keyword CHARSET to set charset at table level.
For example:
CREATE TABLE tbl1 (col1 STRING) ROW FORMAT CHARET "GBK" DELIMITED FIELDS TERMINATED BY '\t';

Another place to use CHARSET is in TRANSFORM clause.
For example:
SELECT TRANSFORM(col1, col2) ROW FORMAT CHARSET 'gbk'
USING 'some_script'
AS (col3, col4) ROW FORMAT CHARSET 'utf-8';
