Wrong interface in dnsmasq.conf inside cobbler container

Steps to reproduce:

1. Start fuel node deployment
2. Press enter on Fuelmenu stage (or add showmenu=yes in grub)
3. Configure fuel to use "eht1" (or any other non "eth0") interface as admin interface.
4. Try to bootrap any nodes.

Result: nodes can't see DHCP.

The problem is caused by /etc/dnsmasq.conf in "cobbler" container, since it has:

interface=eth1

But "cobbler" docker container has only "eht0" and "lo" interfaces. This is why nodes can't get DHCP.

    Use eth0 as dhcp_interface in cobbler container

    Docker containers have only "eth0" and "lo" interfaces by default.
    So if we deploy fuel on any non "eth0" interface, then
    /etc/dnsmasq.conf file will have worng "interface" parameter which
    breaks DHCP discovery. We need to hardcode dhcp_interface=eth0.

fixed: DHCP works fine using eth1
