arm64 support

[dkrizic]

Hi,

I read your article in https://medium.com/better-programming/improve-cluster-monitoring-with-network-mapping-in-grafana-fa8bb479fd47

Thank you for that. I tried Caretta on my hybrid home cluster that has hybrid architecture amd64 and arm64 and I see that you don't provide multi architecture images that run on both architectures.

So please add arm64 support.
