AWS::EC2::VPCPeeringConnection DNS Resolution

## Instructions for CloudFormation Coverage New Issues Template

Quick Sample Summary:
1. Title -> AWS::Service::Resource-Attribute-Existing Attribute
2. Scope of request -> AWS::EC2::VPCPeeringConnection ist missing DNS Resolution Feature for Accepter and Requester
3. Expected behavior -> There should be an option to enable/disable dns resolution for accepter and for requester

As you can see in the Link https://docs.aws.amazon.com/de_de/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-vpcpeeringconnection.html
there is a missing feature to enable Requester and Accepter DNS Resolution.
You can do it with the AWS Console.
And also with the CLI: https://docs.aws.amazon.com/cli/latest/reference/ec2/modify-vpc-peering-connection-options.html

It would be nice to see that feature in Cloudformation

Start by reading the AWS CloudFormation VPCPeeringConnection resource documentation and the linked EC2 modify-vpc-peering-connection-options CLI reference. Confirm the missing requester and accepter DNS-resolution options and determine how CloudFormation should expose them. Done means the resource supports enabling or disabling both options with documented behavior and coverage tests.
