Harald Jensas b6d117fcd5 Allow setting network-segment on subnet update
To enable the possibility to migrate a non-routed network to a
routed network allow updating the segment_id of a subnet.

Only allow the operation if:
 - The network only has one segment
 - The network only has one subnet
 - The current segment_id == None

APIImpact: The segment_id attribute of subnets now allows put operation.
