Description

Currently LegacyTypeInfoDataTypeConverter only support conversion between DataTypes.BYTES and BYTE_PRIMITIVE_ARRAY_TYPE_INFO. When we update connectors to new type system, we need to convert BINARY(p) or VARBINARY(p) to BYTE_PRIMITIVE_ARRAY_TYPE_INFO.  A similar logic has been implemented for CHAR/VARCHAR type.

The Hive connector achieve this via depending blink planner‘s conversion logic, which is odd because a planner dependency won't be necessary for connectors.
