Docker: is the docker image necessary for Pipcook 2.0?

[FeelyChau]

Pipcook 2.0 is light enough, I think we could remove the docker image now.

Cuda environment is also required :)

[FeelyChau]

Maybe we can use office CUDA docker image directly: https://hub.docker.com/r/nvidia/cuda

Hmmm, the cuda image doesn't offer the Node.js runtime.

[FeelyChau]

So the Pipcook image includes CUDA and Pipcook client? Looks not so necessary.

It's good to maintain a Node.js + Cuda image, but it could not be an Pipcook image.
