Bug Description

We need an ability to specify MTU for physnets in Neutron.

Steps to reproduce:

1. Edit a key in quantum_settings to specify MTU for path_mtu and network_device_mtu
2. Deploy cluster
3. Check path_mtu in /etc/neutron/plugins/ml2/ml2_conf.ini

Expected result:
path_mtu = 1200

Actual result:
path_mtu = 1500

    Add ability to override MTU for networks

    * This patch make ability for override ML2/path_mtu into:
          quantum_settings:
            . . .
            L2:
              segmentation_type: tun
              path_mtu: 8000
              tunnel_id_ranges: 2:65535

    Custom noop-test added fot cover this task.
