Subject: [PATCH] Jenkinsfile: run DCO check before everything else

This will run the DCO check in a lightweight alpine container, before
running other stages, and before building the development image/container
(which can take a long time).

A Jenkins parameter was added to optionally skip the DCO check (skip_dco)
