Most of the individual controllers were already converted earlier. Some log calls were missed or added and then not updated during a rebase. Some of those get updated here to fill those gaps. Adding of the name to the logger used by each controller gets consolidated in this commit. By using the name under which the controller is registered we ensure that the names in the log are consistent.
