types/netmap: remove NetworkMap.{Addresses,MachineStatus}

Browse Source 
And convert all callers over to the methods that check SelfNode.

Now we don't have multiple ways to express things in tests (setting
fields on SelfNode vs NetworkMap, sometimes inconsistently) and don't
have multiple ways to check those two fields (often only checking one
or the other).

Updates #9443
