const BurstableCreditsToECUS float32 = 3.0 / 60.0

I believe one vCPU ~ 3 ECUS, and 60 CPU credits would be needed to use one vCPU for an hour

const ClientMaxRetries = 13

By default, aws-sdk-go only retries 3 times, which doesn't give much time for exponential backoff to work for serious issues. At 13 retries, we'll try a given request for up to ~6m with exponential backoff along the way.
