Create a Guide/Template: Create Docker documentation for Incubator

### Overview
We need a guide to building a docker image to deploy software onto Incubator, so that when projects are ready to deploy they know how to make their own docker image.

#### Details
With the Incubator, software and projects are deployed via Docker images. With VRMS, CivicTechJobs, HomeUniteUs, we have a common Django infrastructure and successful docker builds working with Incubator.

### Action Items
The phases in the guide-making process are listed below. Each phase displayed in blue is linked to a wiki page with instructions on how to complete that phase. Open the wiki page in a new tab, copy the instructions for each part into the section labeled 'Tasks' at the bottom of this issue, and complete each task listed.
