AWS::SSM::Parameter - New Return Value

[benbridts]

AWS::SSM:Parameter has the parameter name as the Ref output, but there is no build in way to get the Arn (see also #68). Which means that you have to build the Arn yourself every time (eg. in IAM policies).

Current way to get an Arn

!Sub "arn:aws:ssm:${{AWS::Region}}:${{AWS::AccountId}}:parameter${MyParameterResource}"

Preferred way to get the Arn:

!GetAtt MyParameterResource.Arn
