jinja2 to jinja3 transition

[marcmengel]

First stab at this looks not promising, to wit, from the ChangeLog:

Version 3.1.0
Released 2022-03-24

Drop support for Python 3.6. #1534

So moving up to jinja3 will involve changing away from using the system Python on both
SL7 and Centos8 (which also ships with /usr/bin/python3 version 3.6.8).

So we might want to reconsider...

[shreyb]

Oh - for sure. We don't want to do this right now. We could bundle our own python in the RPM in the future, or otherwise wait for CentOS 9 and see what that landscape looks like.

Should we keep this open for "some future date", or close this for now?

[marcmengel]

If we can mark it for "Future",. I think we should keep it -- I mean, we could rely on a newer devtools python and still do an RPM...

[shreyb]

Done.

We'll need to handle this sometime in the next few months - experiments are already starting to move to EL8 and looking to EL9.
