On some complex (serious) infrastructures, there can tens of allowed networks. These are sensitive data, often modifed, and it can happen that there is concurrent modification on them. So a "replace" only semantic can't be enought:

(client 1 wants to add n3, client2 remove n2)
* STATE on server: [n1, n2]
client1: get all allowed networks => [n1, n2]
client2: get all allowed networks => [n1, n2]
client1 POST [n1, n2, n3]
* STATE on server: [n1, n2, n3]
client1 POST [n1]
* STATE on server: [n1] <= NOT WHAT WE WANT.

So: add a patch command to handle just add/remove some networks.
