Bug Description
When a rack controller registers, it makes a connection to every single region process endpoint. This means one connection for every region controller IP address, multiplied by the number of region processes listening on that IP address.
It's not clear that this many connections are needed; one per process is likely sufficient, though multiple IP addresses may need to be attempted due to reachability concerns.
MAAS racks should only hold open one connection per region process, rotating through the IP addresses as-needed.
