Create a Contributor's Quick Start Guide

[RNHTTR]

It'd be helpful for new contributors to have a quick start guide to help them get up-to-speed quickly. This could potentially be added to CONTRIBUTING.md, but ultimately I think something should touch on how to use up.sh locally for development, e.g. docker/up.sh --seed --build

@RNHTTR: we do have a quickstart for Marquez, but did you have something else in mind?

[RNHTTR]

Yeah, specifically for contributing to Marquez. Maybe a section in CONTRIBUTING.md that touches on the --build flag to build a local image from the developer's current branch
