Arm64 support, including multi-arch amazon/cloudwatch-agent

[scottmalkie]

Hello,

Cloudwatch Agent itself supports Arm64[1], as does fluentd[2].

As EKS and ECS now both support Graviton/Graviton2-based images[3], Container Insights should support them as well.

Thanks!

@scottmalkie I think we can close the issue now? https://aws.amazon.com/about-aws/whats-new/2021/01/amazon-cloudwatch-container-insights-available-aws-graviton2/

Yes! Thanks so much!

@SimonSikstrom I think the prometheus tag is for some old releases, the latest release should contain the code in aws/amazon-cloudwatch-agent#105
