CI Test for out-of-tree quartz application

[davekaj]

Summary

A CI check that tests quartz CLI commands on an application created using quartz init. The idea is to use the docker setup being built to address #144.

Acceptance criteria

• CI job that does the following ->
  • Runs quartz init to create a sample quartz app
  • Runs quartz dev to test the sample app end-to-end

This is basically a test for #170

Need to test that a user can install quartz, and then create a new quartz app (quartz init) in a fresh dir (outside the main quartz repo ) and run everything there.
