VxLAN deployment is limited by GRE limitation

[Alexander Rubtsov]

MOS: 9.2

--- Description ---
Fuel doesn't let to specify segmentation ID higher than 65535 for VxLAN deployment.

--- Steps to reproduce ---
1. Create a new environment with tunneling segmentation

2. Download the network settings:
fuel network --env 5 --download

3. Edit the network settings:
vim /root/network_5.yaml
...
  gre_id_range:
  - 70000
  - 80000
...

4. Upload the modified settings:
fuel network --env 5 --upload --dir /root/

5. Deploy the environment

--- Actual behavior ---
Step #4 (uploading the settings) fails with the following error:

400 Client Error: Bad Request for url: http://10.20.16.2:8000/api/v1/clusters/5/network_configuration/neutron (70000.0 is greater than the maximum of 65535

Failed validating 'maximum' in schema['properties']['networking_parameters']['properties']['gre_id_range']['items']:
    {'exclusiveMaximum': False,
     'exclusiveMinimum': False,
     'maximum': 65535,
     'minimum': 1,
     'type': 'integer'}

On instance['networking_parameters']['gre_id_range'][0]:
    70000)

--- Expected behavior ---
The environment is successfully deployed
The range specified prior to deployment is in Neutron configuration file
# grep "^vni_ranges" /etc/neutron/plugins/ml2/ml2_conf.ini
vni_ranges =70000:80000

Allow GRE ids over 65535

Previously existed a limitation of the maximum GRE id of 65535.
This field is also used in the vxlan scheme which doesn't have
such limitations. Since GRE deployments are deprecated starting
from MOS7.0 it is possible to adjust this field validation allowing
maximum of 2 ** 32 - 1 vxlan ids.
