move some elements out of the the install script and into the Dockerfile
don't use supervisor
use run.sh instead of profile for clarity
don't need cron
mv profile to run.sh
add Rundeck DEB later since Docker won't cache it
make run.sh be the entrypoint
add VOLUMES for stuff we may want to mount externally or keep
update README with better instructions
don't install supervisor or ssh
set pass at runtime, not install time
change MAILFROM at runtime, not install-time
don't need to to fiddle with SSH since we're not using it
