feat(route53): DNSSEC zone signing (#28604)
Browse files Browse the repository at this point in the history
This makes it possible to enable DNSSEC signing for a Route 53 hosted zone. A new `KeySigningKey` construct is created to enable generally creating KSKs. Additionally, an `enableDnssec` method is added to `HostedZone` that provides an easier interface. The later will create the KSK and further create the necessary `AWS::Route53::DNSSEC` resource to actually enable signing on the resource.
