This is to prepare for the upcoming V2 configuration. When we're in V2, we only want to load _upgradable_ configuration keys.
Before we were manually going over every plugin and getting each piece, all over the place. Now we have a central manager that will give us all the pieces we want. There is still some cleanup to do here but this is much better overall.
It was only used in a couple places and it isn't necessary since you can do the loading within the actual blocks themselves.
