Pulp 3 installation playbooks insert junk into server.yaml
Each time a user runs the Ansible installation playbooks, those playbooks insert three dots at the end of
/etc/pulp/server.yaml. These dots signify separations between sections of a YAML document. Pulp 3's configuration file consists of a single section, so dots shouldn't be inserted. The
to_nice_yaml filter on this line of code needs to be dropped.
