Production Dockerfile's base image uri is not following the dev image base uri that builds it

[putcn]

I was using paddlepaddle/paddle:latest-dev to build paddle, whose base is nvidia/cuda:8.0-cudnn7-devel-ubuntu16.04, but the Dockerfile generated in the build directory is nvidia/cuda:8.0-cudnn5-runtime-ubuntu16.04,
also, there is a step as follows:

RUN ln -s /usr/lib/x86_64-linux-gnu/libcudnn.so.5 /usr/lib/x86_64-linux-gnu/libcudnn.so

libcudnn.so.5 should also be libcudnn.so.7

I think we need to track the cuda version number and cudnn version number in our build process and generate corresponding Dockerfiles.

this issue is from #10720

fixed by #10778
