Problem
current httpbin images don't support arm64 architecture. that means we can't run them on AWS Graviton's or Apple M1's natively.
Solution
use buildx to build a multi-arch with
linux/amd64,linux/arm64platform support.the biggest change is we have to go from separate build and push steps into a single build and push step. this is because the local docker doesn't support building locally multi-arch images.
Notes
based on https://www.docker.com/blog/multi-arch-images/ and https://www.docker.com/blog/multi-arch-build-what-about-circleci/
our upstreams,
golang:1.16supports these architectures and more.addresses: #63
