DDF-818 Fixing various bugs contained in the Configuration page

* Switched the backing architecture to the configuration page from Relational to Assocation.
* Fixing an issue where adding a non-factory configuration was causing an entry to not be added to the list.
* FIxing several refresh issues where bad / stale data was being shown.
* Fixed an issue where adding a new entry to the list would not cause the modal to reappear.
There are still several instances where backbone-relation is still being used like Module. I'm not sure we can blanketly remove it without out additional work. I'm not sure about Module, it could need relational for some thing.
