Switch to signer.<region>.iopipe.com hostnames

[kolanos]

API Gateway is horribly broken when it comes to multi region support. So in the meantime we'll need to use signer.<region>.iopipe.com hostnames for the signer, similar to the way the collector works.

@kolanos @fastfiveoh could you all confirm the regions that need to be supported?

@kolanos
We currently support
-us-east-1
-us-east-2
-us-west-1
-us-west-2
-eu-west-1
-ap-northeast-1
-ap-southeast-2

@pselle @fastfiveoh Here's what's deployed:

https://signer.ap-northeast-1.iopipe.com/
https://signer.ap-southest-2.iopipe.com/
https://signer.eu-west-1.iopipe.com/
https://signer.us-west-1.iopipe.com/
https://signer.us-west-2.iopipe.com/
https://signer.us-east-1.iopipe.com/
https://signer.us-east-2.iopipe.com/

@kolanos Thank you! What should I default to in an unsupported state, us-west-2?
