Initial version of the new Docker Build scripts

Successfully builds the container, places the files, scripts and links
we need so fart into the right places using a rootfs tar file so that we
don't pollute the container unneccessarily and keep the Dockerfile
simple.

Any in-container scripting is missing so far, so the whole thing does
not yet start up successfully or popluate the config share in any way.
That is for another day.
