util to request SSL certificates in multiple regions

[andreineculau]

cloudfront and api-gateway (edge-optimized) require certificates to be placed in n.virginia

but other scenarios (e.g. api-gateway regional) require regional certificates e.g. an api-gateway in ireland will only be able to use certificates from the ireland certificate manager

in order to skip a few manual hops, a utility could read the necessary details, request the SSL certificates (and if DNS is the validation method, it can print out the required DNS entries)

another util could read the output from the first util, and make the necessary dns changes. Two utils are needed, not just from the perspective of the KISS principle, but also because requesting SSL certificates may happen in a different account than the one that manages the DNS
