Support for Daemon-Reload

[patchsmyle]

Add to reload the system service files. "systemctl daemon-reload"

Use case:
Adding custom systemd .service or .socket files into /etc/systemd/... requires a reload to see the new service files.

Something to the effect of:

if $name == "systemd"
    <systemd direct service commands>
    systemctl(comm, undef)
else
   systemctl(comm, $name)
end
