    CLOUDSTACK-9086: ACS allows to create isolated networks with invalid …

    …gateway IP address - Fixed
    
    Problem: There was no check for the network and broadcast IP addresses in the case where
we provide the gateway and netmask while creating the isolated network. As a result the provided
IP gets assigned to the eth0 interface of the VR.
    
    Fix: Added the necessary checks.

> When entering invalid combination no check is performed anymore and VR is created with
invalid interface. Of course, nothing works in the isolated network. For example, you are
allowed to create network with 172.16.21.0 IP address for GW and 255.255.255.0 for SM - this
address is not valid, however it is accepted and even used in VR. One more example - 192.168.255.255
for GW address and 255.255.255.0 for SM.
