Bug 1383035

Description of problem:
[OVS] - Can't set a gateway on a 'ovs' network via the setup networks dialog. 

When setting a gateway on network in ovs cluster, it is reported as out-of-sync. Nothing reported for 'gateway' in caps.

- It looks like engine is sending the setup networks command to vdsm and gateway is passed -->

- In supervdsm i can see that gateway is passed for Running config, but it's not reproted in caps -->

Version-Release number of selected component (if applicable):
4.1.0-0.0.master.20161008231308.git39b2133.el7.centos

How reproducible:
100

Steps to Reproduce:
1. Add host to 'ovs' switch type cluster 
2. Attach network to host NIC via the setup networks dialog and set a static ip with gateway

Actual results:
Network reported as out of sync with the host. No 'gateway' reported for this network in VdsCaps

Expected results:
Should work
