Add an ARCH parameter to handle arch specific things

Add an ARCH parameter to handle arch specific things, mostly are the
docker image repo names.

Because not all the docker images magnum used support multi-arch
manifest[1] like kubernetes-dashboard, it will need to specific the
arch name in the docker image repo name.
