The pupose of this package is to pick the best API endpoint for reduced latency.
e.g API endpoint has 3 regional endpoints:
us-east-1 us-east-2 us-west-1
You have an app deployed on us-east-2 You'd want to use us-east-2, but you have to know that ahead of time. Or you select us-east-2, but that service is down at that region...so you'd want to gracefully fallback to us-east-1.. This package is designed to mediate which URI your app should call.
