[FLINK-5832] [table] Support for simple hive UDF
Type: New Feature
Priority: Major
Components: table, udf, hive
Problem definition: Make Flink call Hive User-Defined Functions, support
for simple hive UDFs.
Design:
1. This patch is based on FLINK-5881, we need variable arguments to call
hive udfs.
2. Added a HiveFunctionWrapper to create Hive simple UDFs.
3. Added a ScalarFunction called HiveSimpleUDF to call Hive Simple UDFs.
Use primitive java object inspectors for the simple UDFs.
4. A few modification of type comparation, make type of Object equal any
types.
5. Added a new method in TableEnvironment to rigister hive UDFs.
Impact Analysis:
A new feature, had few impacts on exsting features, except for the
comparation of types.
Test:
`mvn clean verify` is done on local.
