setup-openemm.sh links to undefined environment variables

Thanks for your work!

But I found some issues.

All MYSQL_* environment variables are renamed (I don't know why).

I prepended following lines to /setup-openemm.sh

MYSQL_HOST=${MYSQL_PORT_3306_TCP_ADDR}
MYSQL_ROOT_USER=${MYSQL_ENV_MYSQL_USER}
MYSQL_ROOT_PASS=${MYSQL_ENV_MYSQL_PASS}
MYSQL_USER=${MYSQL_ENV_MYSQL_USER}
MYSQL_PASS=${MYSQL_ENV_MYSQL_PASS}

and then this file executed successful.

Should I make an PR?

And there is no information in README, that after docker-compose up the sh-files from openemm-container should be executed.
