[CUWiN-Dev] Rev. 4085 disappearing default routes

[Bryan Cribbs]

>>> So, the nodeconfig will soon:
>>>   1. attempt to read new keys from it's master file
>>>   2. attempt to read old keys from it's master file
>>>   3. attempt to read keys tagged as "default" from it's master file
>>>   4. fall back on hardcoded values (such as 'domainname.tld').

Minor thing, I think we should swap 2 and 3.

Making the precedence:
1) modern keys
2) default keys
3) legacy keys   (*)
4) hardcoded fallbacks.


(*) legacy keys include 'smart' values, such as hashed ips, and the  
logic that decides if a wireless iface is backhaul/client/ap.   
Nodeconfig doesn't touch such things unless one explicitly changes  
those values via the web interface.  (similarly, the default values  
on dhcp server are based on the ipschema family as has always been  
the case, if they aren't changed).  These keys are removed from the  
default cuw_config, since they are derived.
