AS: An operator wishing to deploy ONAP

I WANT TO: be able to have access to multi-cpu architecture AAF container images

SO THAT: I can choose among several hardware and cloud providers that fit my requirements and needs.

For each container image delivered by the AFF project, modify the Dockerfile, or use a template if available, in order to:

-Specify a base image that is cpu platform agnostic (i.e. Alpine Linux)
-If necessary, modify the Dockerfile instructions to build on at least Intel and arm cpu architectures
-Verify that the container images pushed to the ONAP Docker registry contain layers for at least Intel and arm cpu architectures. (Not yet integrated with CSIT and therefore images have not been pushed)
