        Scenario:
            1. Revert snapshot "deploy_neutron_vlan_ha"
            2. Upload a new openstack configuration
            3. Get uptime of process "neutron-server" on each controller
            4. Apply a new VLAN range(minimal range) to all nodes
            5. Wait for configuration applying
            6. Verify ml2 plugin settings
            7. Create new private network
            8. Try to create one more, verify that it is impossible

        Snapshot reconfigure_ml2_vlan_range

After instigation of the snapshot error_reconfigure_ml2_vlan_range and error_reconfigure_nova_quota it was found that they were revering reconfigure_keystone_to_use_ldap test, not the "deploy_neutron_vlan_ha"
