presence of futures==3.1.1 can break molecule

See original GitHub issue

I discovered that presence of futures==3.1.1 would break ansible/molecule. Removal fixed the issue.

I am not yet sure what installed it so I am unsure how we can prevent it, as it not listed as a dependendecy. Still, it could prove useful to share it.

$ molecule create                                                                                                                                                         --> Validating schema /Users/ssbarnea/rdo/rdo-infra/testproject/molecule/default/molecule.yml.

I have now uploaded a dummy py3 wheel for 3.1.1. Let’s hope this avoids some of the grief caused by bad packaging.

Fixed in two ways. Thanks @agronholm
