remove ProtoData

fix #5769

[luotao1]

76501c8 commit 删除了config_parser.py中的ProtoData，但没有删除Chunk.conf中的。然而test_Trainer.cpp的单测依然能过，原因是：

add_test(NAME test_Trainer
  COMMAND ${PADDLE_SOURCE_DIR}/paddle/.set_python_path.sh -d ${PADDLE_SOURCE_DIR}/python/
        ${PYTHON_EXECUTABLE} ${PADDLE_SOURCE_DIR}/paddle/trainer/tests/gen_proto_data.py &&
        ${PADDLE_SOURCE_DIR}/paddle/.set_python_path.sh -d ${PADDLE_SOURCE_DIR}/python/
        ${CMAKE_CURRENT_BINARY_DIR}/test_Trainer
    WORKING_DIRECTORY ${PADDLE_SOURCE_DIR}/paddle/)

导致运行gen_proto_data.py成功后，就返回。没有运行后面的test_Trainer。运行结果如下：

e131e96 将chunk.conf和对应的gen_proto_data.py删了，原因有两方面：

• 使test_Trainer单测正常运行。
• 因为ProtoDataProvider很久都没有人使用，将gen_proto_data.py里的逻辑用PyDataProvider写比较耗时。同时，test_Trainer单测中一共比较了4个config，去掉其中的一个，对整体测试逻辑没有较大的影响。

Love to see the removal of big chunks of data files!
