feat: quantized tensor support (#1611)
* feat: quantized tensor support QuantizedTensor inherits from Tensor with supporting part of methods. The memory is allocated from native code, so it only matains a pointer `getNativeStorage`. Note, We don't support automatically `free` method. Anyone using this method should think about the memory lacking, especially for memory optimization. test: quantized tensor tests * fix: test case failed on spark 1.6
