One should be able to change ovs port type if its not virtual.

If ovs port is virtual, we use OVSIntPort to create it.
Otherwise it should be OVSPort.
I've added new key: ovs_port_type to not intersect with current
deployments and not hurt anyone.

I've updated doc to have an example of ovs peering patch.
