Publish and test arm docker images for every PR

[friedrich-at-adobe]

Is your feature request related to a problem? Please describe.
Many users are already trying to use cortex with ARM.

Describe the solution you'd like
For every PR we should run tests in ARM and Intel.

Describe alternatives you've considered
I don't think there is an alternative, we have to support natively what users are doing.

There is already some support in:

cortex/Makefile

Several of my customers at AWS have asked about this. Is there anything I can do to help move this along? I can provide arm64 build resources if needed.

[alvinlin123]

Currently we only publish ARM for build images. We still need to build the actual Cortex image for ARM.

@alvinlin123 I'd like to help produce the multi-arch image and publish it. I can provide ARM build resources for you as needed.

[alvinlin123]

@otterley do you mean you have someone who can work on updating the build workflow?

I have not dive deep into what needs to be done, but at high level I think it involves making some modifications to the GitHub Action workflow. If you work on modifying and testing the workflow, I can provide some guidance on what I know :)

@alvinlin123 Let's take this offline - can you email me at fiscmi at amazon ?

Hi, is there any movement on this? My company is looking to move some infra to AWS Graviton instances, and would love a native arm64 image for this. With 1.14 coming out soon, it would be a good time to start.
