scenario001 https://storage.gra.cloud.ovh.net/v1/AUTH_dcaab5e32b234d56b626f72581e3644c/zuul_opendev_logs_c83/732091/2/check/tripleo-ci-centos-8-scenario001-standalone/c83b01f/logs/undercloud/home/zuul/standalone_deploy.log

this broke scenario001/004 because ceph-ansible is getting the callback settings carried through. Unfortunately ceph-ansible doesn't have out callback locations loaded when it's getting invoked so it errors. We need to fix the ceph-ansible invocation to either load our tripleo-ansible paths or not set stdout_callback/callback_whitelist.

we can revert the enablement and fix ceph-ansible later

    Exclude callbacks env vars for ceph-ansible

    We're working on changing the default callbacks for tripleo but we don't
    want to use them when invoking ceph-ansible. We should exclude the
    callbacks that were used in the calling env and specifically set the
    regular callbacks.
