Dockerfile states configuration file is not taken into account by default

[KoltesDigital]

This project's README states that one can use their own config file without changing the command:

1. You may either specify your own configuration file instead.

   docker run -d --network=host
   -v $(pwd)/my.conf:/etc/coturn/turnserver.conf
   instrumentisto/coturn

However, the CMD puts the -n flag, which disables reading from any config file.

coturn-docker-image/Dockerfile

Line 114 in 437c26a

CMD ["-n", "--log-file=stdout", "--external-ip=$(detect-external-ip)"]

I suspect the flag is here because coturn fails to start if it can't find a config file. If it's the case, I suggest removing the above section from the README. If not, I suggest removing the -n flag.

FTR, I found this issue because I observed my config file was not taken into account. By adding -c /path/to/turnserver.conf it is.
