OpenStack VM had 4 interfaces, from which eth0 was connected to HIMN (Host
Internal Management Network), and not used at all. The reason for not
using this interface according to johngarbutt is:
- VNC console would not work
- migrations would not work
- many other things
This change removes the interface, thus devstack is providing the
same architecture as described in the official documentation, YAGNI
applied on the HIMN:

The change also modifies some defaults, so it's easier to get started:
- The Ubuntu VM is network-installed through the management network
- OS VM is getting its address on the management network through DHCP
- Default Public IP addresses aligned to stack.sh defaults
- OS Services are listening on Management Interface
