Issue #45 docker

[ssilverm]

Proposed Changes

This Dockerizes Quiz Extensions.

Resolves #45

[Thetwam]

Need to add FLASK_APP and FLASK_DEBUG environment variables

Tests fail because the template for config.py is missing. Need to update run-tests.yml to support the new setup.

I noticed HTTPS isn't supported. I would like to retain that functionality.

Also, status page is now failing to load index and xml pages:

Traceback (most recent call last):
  File "/usr/local/lib/python3.7/site-packages/urllib3/connection.py", line 175, in _new_conn
    (self._dns_host, self.port), self.timeout, **extra_kw

    raise err

    sock.connect(sa)
ConnectionRefusedError: [Errno 111] Connection refused

Need to pull in latest develop, address conflicts, and address comments above.
