Request for additional SCM Import/Export documentation

[tw102609]

We're leveraging the SCM Import Export plugin in Rundeck which is helpful to push and pull jobs from the local Rundeck instance to Github. There is limited documentation here but there is not a description of what the "clean" functionality does when configuring. It may be helpful do developers to add this information on this page.
