Satellite Customization with /etc/foreman-proxy/custom-hiera.yaml

This is a very useful tool for configuring persistent security settings on the various components of Satellite. The document (https://access.redhat.com/articles/2951701) only mentions a few of the components though.

Presumably we can configure almost any setting of almost any component of Satellite. I haven't ventured much outside of QPID and Apache. I was just wondering if anyone has had a use case for configuring connection settings and/or authentication type settings of the databases (mongo/pgsql) and what the result was.
