Write Python script to simulate client interface

[Raghav-B]

Sub-task of #1 .

Use Python websockets module to simulate the following functionality from the client frontend

• user-login: Available in frontend signallingServer.userLogin()
• find-robot: Available in frontend signallingServer.findRobot()
• offer: Available in frontend signallingServer.sendOffer()
• user-start-game: Available in frontend signallingServer.startGame()

The login for what the client does in each functionality is provided in the frontend GameSelect.js in goToBattle() and Home.js when the start button is pressed.

Spawn multiple threads that perform the above functionality so we can stress-test the queuing system.
