Add example YAML for loggerconfig option

It's really difficult to find documentation on what needs to be in the optional ini, yaml, or json files.
This snippet comes out of the test case from the source code.

It should, at least, give people a place to start when using this option.
I was under the impression it was required for YAML documents.
But I guess that is only the case when there are multiple docs in the same
file.

Would you like me to update?
