Prebuilt docker image for aarch64

[Binyang2014]

We don't know the base image for Kunpeng CPUs. If you want to build image for Kunpeng manually, you need to change https://github.com/microsoft/pai/blob/master/src/<servicename>/build/<servicename>.common.dockerfile. And change the
FROM ... sentence.

Since we don't verity if the components work in arm architecture, this change may cause some components failed.

@Binyang2014 Thanks. I think the ubuntu base image would work. It has arm64 version. Do we have any documents about how every docker image is built?
