Update helios_server/helios_server

this is the init script to start helios server in daemon.
In this init script I have assumed that the master folder (helios-server) is located in /opt.
if the location is anywhere else then you just have to change
DAEMON=  python /opt/helios-server/manage.py runserver 0.0.0.0:8000
to DAEMON=  python "your helios-server location"/helios-server/manage.py runserver 0.0.0.0:8000
