ValueError: Invalid value for `dhcp`, must not be `None`

# Description

Corellium SDK version installed via `pip`: `corellium-api>=0.4.0`

When using any version of the SDK >= `0.4.0`, a regression in the `v1_get_project` occurs.

This is my code that is reproducing the error:
```python
from __future__ import print_function

import asyncio
import corellium_api
from corellium_api.rest import ApiException

HOST = "https://***.corellium.com/api" # redacted

configuration = corellium_api.Configuration(host=HOST)
configuration.access_token = "***" # redacted

async def main():
async with corellium_api.ApiClient(configuration) as api_client:
client = corellium_api.CorelliumApi(api_client)

project = await client.v1_get_project(
project_id=""
)
print(project)

if __name__ == "__main__":
asyncio.run(main())
```

When running the code above, this produces a `ValueError`:
```python

ValueError: Invalid value for `dhcp`, must not be `None`
```

This doesn't appear to happen on the SDK version `0.3.2`:
```python
{'id': '',
'name': 'test-name',
'quotas': {'cores': 6.0, 'instances': 15.0, 'ram': 36864.0},
'quotas_used': {'cores': 0.0, 'gpu': 0.0, 'instances': 1.0, 'ram': 0.0},
'settings': {'dhcp': None, 'internet_access': True, 'version': 1.0}}
```

Start by reading the generated `project_settings.py` model and the deserialization path shown in the traceback for `v1_get_project`. Compare the `dhcp` handling with SDK version 0.3.2 and reproduce the request with the supplied example. Done means a project response with `settings.dhcp` set to `None` deserializes without raising this `ValueError`.
