Enable users to set flags when executing the Docker image for customizability

[gridhead]

The frontend service provides a lot of myriad options for the users to tweak.

(venv) [t0xic0der@ToxicDragon supervisor-frontend-service]$ python3 main.py --help
Usage: main.py [OPTIONS]

  Main function

Options:
  -p, --portdata TEXT  Set the port value [0-65536]
  -6, --ipprotv6       Start the server on an IPv6 address
  -4, --ipprotv4       Start the server on an IPv4 address
  --version            Show the version and exit.
  --help               Show this message and exit.

Although the default settings work just fine, the correct way of execution would be by providing flags to the users for image execution.
