undeploy should remove Route53 entries if the distribution matches

[Miserlou]

Currently this must be done manually

It looks like you also have to go to the API GW and remove the Custom Domain Names entry. I did the manual removal in API GW and R53 but still get this error:

Waiting for DNS to propagate..
An error occurred (BadRequestException) when calling the CreateDomainName operation: The domain name you provided is already associated with an existing CloudFront distribution. 
Remove the domain name from the existing CloudFront distribution or use a different domain name. 
If you own this domain name and are not using it on an existing CloudFront distribution, please contact support.
Failed to generate or install certificate! :(

I did both manually (Remove Route 53 entry, and API GW Custom Domain), and am now experiencing the same problem as @mcrowson trying to certify a new domain. Any tips? I might be able to send a PR, if the maintainers could give some guidance. I'm using the latest zappa version on pypi.

After manually removing the custom domain name, you have to wait about 40 minutes until you can certify again. Most changes to CloudFront (the backend for the custom domain name feature) take anywhere from 20-40 minutes to be pushed out across Amazon's edge network.
