[Pulp-list] 502 Bad Gateway error connecting to new pulp instance installed with pulp_installer

Using pulp_installer 3.5.0 and this:

  roles:
    - pulp_all_services

also produces the version compatibility error (posted above) like I was
getting using 3.4.1 which uses a different role pattern:

  roles:
    - pulp_database
    - pulp_workers
    - pulp_resource_manager
    - pulp_webserver
    - pulp_content

I will file a bug.
