Runbook specific variables
Add variables to Runbooks, so that adding new variables to the project for a specific Runbook don't cause the snapshots of other Runbooks to be old.
For example, we have a Runbook that exports data from a database to a CSV and emails it. We have variables for the from and to dates and the email addresses to send to. The from/to dates are prompted variables, so you can do an adhoc run. If no dates are provided, it will default to the last week of data.
These variables only have meaning for this Runbook, so it would be nice to define them for the Runbook.
