    Changes look good @shuai-xu. I have a single last question which is whether we want to
expose the `GpuResource` to the user or not. Wouldn't it be enough to set the gpus via `Builder#setGpuResource(double)`?
Of course, then we weren't able to set the `ResourceAggregateType` but I'm wondering whether
GPUs shouldn't be something else than the sum. We actually have the same problem with the
cpus. They are hardcoded to be the max of both values.

> Now, flink only support user define how much CPU and MEM used in an operator, but now
the resource in a cluster is various. For example, an application for image processing may
need GPU, some others may need FPGA. 
> Only CPU and MEM is not enough, and the resource type is becoming more and more, so we
need to make the ResourSpec extendible.
