Require image for ARM64 architecture

[odidev]

Hi Team,

I am trying to use the amazon/amazon-ecs-sample image on arm64 platform but it seems it is not available for arm64.

I have successfully built the image using the command docker build -t image_name . on the arm64 platform without any changes in the Dockerfile.

I have used Travis-CI to build and push the image for both the platforms.

Do you have any plans on releasing arm64 images?

If interested, I will raise a PR.
