AWS::DynamoDB::GlobalTable - GetAtt support for replica table attributes

Create additional GetAtt attributes that include the ability to get any replicas StreamArn and additional properties as needed (e.g TableId)

-----
I am trying to create a global table and I will need the streamArn from all the replicas. There is a way to get that?

Right now I am trying to export the stream arn in the cloudformation template, but I can only access the region where this template is being deployed.
I want to be able to access this values in another cloudformation template

I am aware that the streamArn id is different in both replicas (the end part of the streamArn), so I can't construct it either.

The issue concerns AWS::DynamoDB::GlobalTable GetAtt support for replica attributes, especially each replica's StreamArn and possibly TableId. Start by reviewing the current supported resource attributes and the linked original discussion; done requires a defined set of replica attributes that can be accessed across CloudFormation templates.
