default gateway configuration fails in fuelmenu

[Gil Meir]

My topology:
port 1 - connected to the pxe network.
port 2 - connected to the public network .

On fuelmenu when configuring eth1 (port 2 for public network) the ip address and netmask are set correctly,
but the default gateway isn't configured.

To workaround this I shifted to another tty and edited /etc/sysconfig/network-scripts/ifcfg-eth1, I added GATEWAY=<my_gw>,
then /etc/init.d/network restart, and it worked.

Afterwards I launched fuelmenu again, amd it showed the correct gateway address. Then I tried to configure the gateway again via fuelmenu and saw the same behavior again - the gateway address was removed from the network-script file and fuelmenu showed "Gateway: None".

Even more, if you will unset default gateway on eth0 - you wont be able to setup gateway for any interface.
Also in my opinion configuration is misleading, you definetely wont be able to setup multiple defaut gateways.
But you should be able to add custom routing for each of the networks, for example,
after modification of network_scripts you will loose routing for admin_network, and all the networks will have gateway
from eth1 as next hop address

I haven't mention it, probably I should have - I deleted the old default gw before manually adding the correct one.
I'm now using another iso, but as far as I remember the routing table after my work around looked like this:
10.20.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
0.0.0.0 <public-net> 0.0.0.0 UG 0 0 0 eth1

Regarding losing connectivity to fuel network - I did it from a console via IPMI interface (out of band), so no problem here.

Fix proposed to branch: master

Raising priority because it's reproducable and affects all deployments.
