[Arm-dev] Official docker containers are now available for AArch64/ARM64

As of the release of 7.4.1708, the official centos docker containers are
now available via multiarch support from the docker hub. For those of
you who have been using the centos/aarch64 namespaced base container,
you can now use 'FROM centos' as the proper method.

I'll keep the centos/aarch64 container around for a little while longer
to give people time to migrate.

TL;DR: 'docker pull centos' now does the right thing, and provides the
image appropriate for your architecture.
