New Check: Amazon Route 53 Latency Resource Record Sets

[brittandeyoung]

Summary

Checks for Amazon Route 53 latency record sets that are configured inefficiently.

Motivation

If you create only one latency resource record set for a domain name, all queries are routed to one Region, and you pay extra for latency-based routing without getting the benefits.
