export SECRET_KEY in docker-entrypoint.sh takes precedence over SECRET_KEY in /etc/alertad.conf

[kucerakk]

In case I do not pass ALERTA_SVR_CONF_FILE to the container the following export SECRET_KEY in docker-entrypoint.sh takes precedence over SECRET_KEY setting in /etc/alertad.conf

docker-alerta/docker-entrypoint.sh

Line 22 in bee0a4d

export SECRET_KEY=${SECRET_KEY:-$(< /dev/urandom tr -dc A-Za-z0-9_\!\@\#\$\%\^\&\*\(\)-+= | head -c 32)}

I believe the env variable should be unset SECRET_KEY after generating minimal alertad.conf
