Bug Description

My understanding was that ListNodePowerParameters was no longer used provided that we have the information in the database. However, while debugging a MAAS i noticed it still was and it was constant:

This is not what you think it is. This is the rack controller asking the region controller, "hey do you have any machines I need to perform a power check on?". When the region controller does have machines that it wants the rack controller to check, it will return a list of machines w/ power parameters to check the power information.

This is *NOT* the RPC called used to get the power driver information from the rack controller.
