Describe the bug
When I attempt to add a bigquery database connection I received the following error in the UI
ERROR: {"error": "Connection failed!\n\nThe error message returned was:\nHTTPSConnectionPool(host='', port=443): Max retries exceeded with url: /token (Caused by SSLError(SSLError(\"bad handshake: Error([('SSL routines', 'ssl3_get_server_certificate', 'certificate verify failed')],)\",),))"}

Upon further investigation, I attached to the docker container as root:
docker exec -u 0 -it <id> /bin/bash and then ran python`

Terminal session:
`Python 3.6.8 (default, Mar 27 2019, 08:49:59)
[GCC 6.3.0 20170516] on linux
Type "help", "copyright", "credits" or "license" for more information.

import requests
From cffi callback <function _verify_callback at 0x7f5b1eccc378>:

raise exception_type(errors)
OpenSSL.SSL.Error: [('SSL routines', 'ssl3_get_server_certificate', 'certificate verify failed')]

I found that I can successfully connect to bigquery or any other https connection via python by running this pip removal.

pip uninstall pyOpenSSL

To Reproduce
Steps to reproduce the behavior:

  1. Go to add databases
  2. Click add a bigquery://
  3. see error message

Expected behavior
I install the docker-compose template and everything works without hackery.

I'm not sure what the solution is here, but thought I'd report it.
