Add AWS inter edge location latency

[juddgaddie]

AWS Global Accelerator uses a global network of 119 Points of Presence in 94 cities across 51 countries.

Would be good to see the latency between those end points just like latency between regions.

Are you looking for:

1. Latency between the POPs themselves? Or
2. Latency between each POP and each AWS region?

I can see a use case for 2 - I am interested in hearing more about the use case for 1.

Thanks!
