One thing that we'll also do on that day is to ensure that 
cico-workspace image will be updated to have duffy client available .
As we never received feedback for that image (see 
https://lists.centos.org/pipermail/ci-users/2022-June/004554.html) that 
means that ansible-core will be replacing ansible (no collection 
embedded in that image)
