Requests a public certificate from AWS Certificate Manager, using DNS validation.
The hosted zone ID must refer to a **public** Route53-managed DNS zone that is authoritative
for the suffix of the certificate's Common Name (CN).  For example, if the CN is
`*.example.com`, the hosted zone ID must point to a Route 53 zone authoritative
for `example.com`.

@param {string} requestId the CloudFormation request ID
@param {string} domainName the Common Name (CN) field for the requested certificate
@param {string} hostedZoneId the Route53 Hosted Zone ID
@returns {string} Validated certificate ARN
Requests a public certificate from AWS Certificate Manager using DNS validation . The hosted zone ID must refer to a ** public ** Route53 - managed DNS zone that is authoritative for the suffix of the certificate s Common Name ( CN ) . For example if the CN is * . example . com the hosted zone ID must point to a Route 53 zone authoritative for example . com .
