[Unlock settings tab] Neutron Advanced Configuration was not updated to deployed one after invokation load latest deployed configuration

[Tatyanka]

Steps to Reproduce:
1. Deploy any cluster without neutron DVR(all boxes from Neutron Advanced Configuration are unchecked)
2. For ready environment go to network settings tab
3. Change VLAN ID range for l2 neutron settings to 1020 press save settings button
4. Enable neutron DVR and Neutron QoS in Neutron Advanced Configuration and press save settings button

 "neutron_advanced_configuration": {
       ....
            "neutron_dvr": {
                "description": "Enable Distributed Virtual Routers in Neutron",
                "label": "Neutron DVR",
                "restrictions": [
                    {
                        "networking_parameters:segmentation_type != 'vlan' and settings:neutron_advanced_configuration.neutron_l2_pop.value == false": "DVR requires L2 population to be enabled."
                    }
                ],
                "type": "checkbox",
                "value": true,
                "weight": 20
5. Press load latests deployed configuration button

Expected:
Vlan range were replaced with value from latest deployed configuration
Neutron advanced data were reset as well (so become unchecked)

Actual:
Advanced data were not back, so DVR and QoS are enabled.
