Support using GitHug in the classroom

[odiraneyya]

A merge request will be offered which:

• provide students with an easy way of running GutHug using a containerized application
• provide teachers with a way to customize levels in a forked repo tailored to their course
• provides a way for teachers to collect data to grade students from the containerized application

Currently, the files suggested for grading are:

• the .profile.yml file used by GitHug to track the current level
• an additional history log that can help teachers understand the students methodology and troubleshooting strategy
