Create symlink Dockerfile to read Heimdall app logs

[asingla76]

create symlink between Heimdall log directory and the /dev/stdout and /dev/stderr in the Dockerfile, so that Docker daemon could pick those by default.

RUN ln -sf /dev/stdout /var/log/production.log
&& ln -sf /dev/stderr /var/log/production.log

Would you be able to put in a pull request with these changes?

[asingla76]

Sure what branch we have the changes in?

That would require you creating a fork of the repository, making the change, and then putting up a pull request up against the project.
