Remove drf-addons dependency.

[sumit4613]

Describe the feature you'd like

We need to remove drf-addons dependency from this project as we're only using it's minor features only.

We will rewrite these 2 methods:

• get_client_ip
• send_message

And we'll remove usage of JsonResponse. Use DRF's Response or something.

Please write tests. 🙏🏼
