Let's move this enum to `Resource`

> 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.
