web socket enhancement

[Hammad887]

1. Implemented Web Socket for real time notifications.
2. Unit tests written for the web socket package
3. Made some changes in swagger.yaml and db layer (Found some issues with CRUD operations while testing)
4. Implemented Validation Checks to make sure only authenticated users can enter and send message to a particular chatroom.

I have uploaded a small video to demo the functionality. Here's the link: https://drive.google.com/file/d/1l31IjJrvoWk9nmKk_Wq9_xtkHosbXgx2/view?usp=sharing

Hammad, that's impressive.

1. But I didn’t see any authentication being performed at the beginning. You didn’t provide any credentials, etc. did you do it before making the video?
2. Could you create a third user and connect that user to a different chatroom and then send the message in the chatroom where first and second user are present? Now, this third user shouldn’t receive the message since this user is not a part of the chatroom where the message was sent.

@shahzadhaider1 Yes, I did the authentication before making the video. Also, here's another video for the 3rd user you wanted me to create and test with the previously made chatroom. Link: https://drive.google.com/file/d/11YbK8n_fTDpPK8bKAxlg9wGoZyLLb9RB/view?usp=sharing

Alright, good work.

Good work! Kudos to @Hammad887 for putting a lot of effort into it

@shahzaibaziz I have changed all the filenames to snake case. Thank you so much for imparting this knowledge. Also, added a websocket handler which addresses most of the changes you asked me to resolve in the websocket-server.go file in the previous commit.

I will need to discuss the dockerfile and docker-compose on a call once everything else gets resolved.
