Faster IP in subnet check This change removes the conversion from IPNetwork to list in one of the router scripts. This makes the router faster at processing static NAT rules, which can prevent timeouts when attaching or detaching IPs. With the `list` conversion, it has to potentially check a list of 65536 IP strings multiple times. We assume that the comparison implemented in the IPNetwork is far more efficient. We have seen speed-up from 218 seconds to enable static NAT with 18 IPs on the router to 2 or 3 seconds by removing this cast. This also fixes a potential bug where adding IPs to a router time out because the scripts are taking too long. 218 seconds, for example, is beyond the timeout on the KVM agent for script execution, and then all enableStaticNat operations will fail.
