[REQUEST] Workflow Previews for Deployed Workflows #224

Is your feature request related to a problem? Please describe.
Right now, we detect when a workflow is different than the version that is deployed, and we capture the deployed state in the db.

Describe the solution you'd like
We should show a preview of that deployed state to the user, so they can see what is different, and give them the option to revert back to that state, view that state, and redeploy (similar to what we have now) their current state so it overrides the deployed state. We already have workflow-previews, so we can just re-use that component from the marketplace to render and display the deployed state.
