The DCO currently resides in an own directory creating a pointless
additional click/tab in order to reach end read it. It also just
clutteres the directory structure of the project.
Therefore this patch provides moves the DCO into an own legal section in
the docs directory, which is hopefully a more reasonable place.
This section can also be extended in future in order to host other legal
documents as well.
