[qa][devstack] Moving to release specific nodesets and jobs for Fedora

Hello all, $subject has come up with the last couple rounds of changes introducing support for the latest version of Fedora within devstack. I've pushed a change introducing version specific nodesets and jobs for Fedora 31 as a way of starting a discussion around this ahead of the PTG: WIP Fedora: Start using version specific nodesets and jobs https://review.opendev.org/#/c/719775/ I'm personally on the fence about this as while it would be nice to have version specific nodesets and jobs it does introduce a lot of churn with each new release of Fedora across many projects: http://codesearch.openstack.org/?q=fedora%5C-latest Cheers, -- Lee Yarwood A5D1 9385 88CB 7E5F BE64 6618 BCA6 6E33 F672 2D76
