Support for Custom Domains and TLS Certificates

You can now create an API gateway with the custom domain name that you specify when you request a custom TLS certificate from a Certificate Authority.

To enable API gateways to use a custom TLS certificate, you create an API Gateway certificate resource comprising the custom TLS certificate, any intermediate certificates, and the private key used to generate the TLS certificate. You then specify that API Gateway certificate resource when creating a new API gateway.
