There were problems on my Ubuntu VM with the target run level that I was
using, so I went for the default. Now, if I restart my VM, the Bridgehead
is successfully started automatically.
Also added some status-generating commands to the run.sh and stop.sh
scripts, so that it looks like they are doing something.
This comprises of the service file to be copied into the systemctl directory,
plus Bridgehead start and stop scripts for both systemctl and for the
administrator on the command line.
