Provide metadata to identify to which SWF construct a given process definition node is associated to

Serverless workflow is parsed into process definitions. The parsing is not one to one. A SWF construct might produce several process definitions nodes.
UI tooling needs a way to track the execution of a process instance againts a SWF diagram.
In order to know at runtime which is the state, branch or action associated to a particular node, the proposal is to add metadata to the node with the action, branch and state name.
This way, nodes not having any metadata can be ignored.
This epic has been added to centralize different JIRAS for different components in one place.
