https://opendev.org/zuul/zuul-jobs/commit/c4c69586223ecc49e3986a5e82d7090e8f6622e7 - causes centos8-master/deps to be installed on RHEL 8 CI nodepool nodes when the multinode bridge role is used. This happens during multinode jobs, and all jobs that parent off multinode (including standalone).
When testing OSP-16 on RHEL 8, the jobs fail at installing packages due to a package conflict:

2020-03-26 21:42:32 | (try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
For standalone jobs, there is a workaround as the bridge is not actually used. The openvswitch packages can be deleted before rhos-related repos are installed.
For mulinode jobs, this above workaround is not possible as the bridge is actually used.
