[Contrib] Workshop at SCaLE 18x

Just a meta thread to discuss what we want to pull together for the workshop at SCaLE. https://www.socallinuxexpo.org/scale/18x/presentations/hands-open-source-way is live. This is the issue tracking the materials; we probably want individual issues per item with dependencies looped in to make sure we get things ready in time: https://github.com/theopensourceway/guidebook/issues/14 I just made this as our own landing page: https://www.theopensourceway.org/wiki/Workshop_SCaLE18x_20200306 (If you don't have a wiki account--and you probably don't--just let me or any account holder know, all users can add new users, otherwise it's locked down for new accounts.)
