add subplugin field support and new Cloud Artifact class

. add subplugin field to integrate with Distribution framework
. add new Cloud Artifact which is to be used by subplugin like k8s
. update test .json file to include reception and forward fields
. add dummy test class to ensure the flow works as expected
. fix typos
