Multi-arch images for echoserver
Originally from:
https://github.com/kubernetes/ingress-nginx/tree/master/images/echoheaders
Moving the code here to prevent bit-rot and to be sure we can recreate
or update the images on demand. Moving it here also ensures we can use
the common harness to build the multi-arch manifests needed for running
the e2e test that use this container.
