MicroByte Title: TrafficCop - Learn Load Balancer using HAProxy

Improvement Proposal: Currently, the application servers are manually need to be spin up and requires flask dependency for it which may cause dependency conflict if user has already installed python and flask with different version.
A docker-compose file would help to automate the spin up of the servers with different ports only with a single command.

Benefits of proposed improvements:

1. Spinning up server will be automated using docker-compose
2. Learners will get an opportunity to learn docker-compose and it's applications.
3. Will prevent any conflicts with python version and flask version.
