Template file without parameters fails in v2

The resource.paramter_file is passing Null value when there is no parameter file for a given template. The manifest.yaml is inherited from version 1 repo.

This forces the template files to have a parameter.

One of the properties parameter_files or parameters is required for the pipeline to generate an event with the parameters for the state machine. We can add this as a feature request to make these properties optional. I think this may add burden on the user to validate the template has default value for all the parameters in the template.

Please give a thumbs up this comment if this feature is applicable to you. Thanks.

Thanks @cabjas01 for confirming. The new manifest version supports deploying StackSet without parameters or parameter_file property.
