Remove future dependency

[Fryguy]

We are using bambou through the vspk library in the ManageIQ project, and it brings in the future library. Recently CVE-2022-40899 came up and we are having trouble upgrading because the support of future seems to be in question since most projects have already moved to python 3.

I'm not a python expert, but would it be possible to remove the future library?

For a little detail on our issue, while the future team released has released an 0.18.3, we are installing through rpms, and python3-future 0.18.3 doesn't seem to have updates on el8 from Red Hat. It's available on epel9, but not epel8, and unfortunately, we can't upgrade to epel9 just yet, so we're kind of stuck.
