Salesforce API TLS "Verify return code: 20 (unable to get local issuer certificate)"

Starting at Tue 2018-02-06 6:23pmPT we noticed a regular background job which connects to the Salesforce Bulk API via Python client started failing with the following message:

SSLHandshakeError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:661)

I am able to reproduce the failure to verify (and therefore connect to the API) from outside Python, using the openssl s_client command.
