PSPNG Full-Sync: Automate a full-sync when first instantiated

When a PSPNG provisioner is first created, it will have missed some/all the historic changelog events and, therefore, it will likely have some catch-up work to do. The idea here is to automatically do a Full-Sync when the provisioner is instantiated.

Chris, How can a changelog consumer tell if it is New? Perhaps query the grouper_loader_log table to see if any instances of it have ever completed?

Please assign this back to me with that guidance on how to identify Newness.

Thanks, Bert
