Heads up: creating a branch for YETUS-1138

[Allen Wittenauer <aw...@apache.org>]

Just a heads up:

	I need to test docker hub’s built-in multiplatform building capabilities.  In order to do this testing, I need to create a branch in the apache repo since it requires an enterprise account and therefore can’t use my own stuff to test.

	As a side note, so far the biggest issue I’ve had with building the Yetus container on M1 has been hadolint as the author doesn’t have an arm64 build readily available.  I’ve also been able to build both x86_64 and arm64 on my machine simultaneously which is pretty nifty.  Now to see if it works automatically via docker hub….

Just as a follow-up:

	- I have arm64 working on my MBP M1 w/the exception of hadolint
	- building both amd64 and arm64 simultaneously took a very long time and never really finished, but this was likely due to memory exhaustion
	- Docker hub builders are broken for multiarch
	- Github builders work and much faster than my MBP. :D

Two PRs opened to enable this:

	- https://github.com/apache/yetus/pull/238
		- enabled other architectures in the Dockerfile
		- with the correct incantations, will multi build via hooks/build
	- https://github.com/apache/yetus/pull/239
		- enables multi build for amd64 and arm64 on GitHub
		- pushes results to ghcr.io/apache/yetus(-base):(foo) on main and tags
		- docker pull (private GitHub repo)/yetus:main does pull down amd64 or arm64 as appropriate
