[PATCH 3/3] systemd: add scripts for running the aiaiai processes

[Jacob Keller]

This patch adds systemd scripts used for running aiaiai-email-dispatcher, and
for running the aiaiai-watch-queues script. I chose systemd as it is used on
several modern Linux distributions. systemd scripts are relatively easy to
create.

There is a unit file for the dispatcher, and a unit file for the queue
process. I also created a unit file triggered when these units fail, which
causes an email to be sent to an administrator.
