Code Issues Proposed changes

Docker build environment does not exit cleanly. 

Our docker builder runs services under systemd.
Systemd requires SIGRTMIN+3 to trigger a clean exit.
The 'docker stop' command will send SIGTERM by default,
which systemd ignores.

Failure to exit cleanly results in mounts being left in
place, and ultimately the container will get stuck in
'Removal in progress' state, and a docker image that
can't be removed.
