In order to allow the new rich deps that rust packaging requires we need
to update rpm on the builders to a version that has backported support
for 3 new rich deps. It needs these at srpm generation time to
understand the new rich deps.
ignatenkobrain has created a rpm with this backported patches and has
promised to update it as needed. When we update builders to f27 after
the release we will no longer need it, so it's only for a few weeks.
We updated staging builders and tested and all looks good there.
So, I would like to:
koji move-build f26-infra-stg f26-infra rpm-18.104.22.168-1.fc26.infrastructure
update rpm on all the prod builders.
In the event this causes a problem we can downgrade them back and/or get
a fixed version.
