As a user I clone a template story And then I add it to my client project And I see a relationship between the template story and the client instance story

Problem:

Please include a detailed description of the problem this feature would solve.

As an admin I want to be able to keep a relationship between a template story and a client instance story So that I can later get insights from past upgrade projects

Resources:

Let's say that there is a story (https://points.ombulabs.com/projects/181/stories/3334) in a template for a version jump (4.2 to 5.0) and I go ahead and clone that story for a new client project.

Then I would expect to see a relationship in the database that connects the template story to the instance story.

In the future, one would get insights from other client projects.

A person who is working on estimate an instance of https://points.ombulabs.com/projects/181/stories/3334 could talk to client project Acme's team and ask them about their experience with it.

I will abide by the code of conduct
