Detailed Description

This configuration class is to set up OnlineFeaturePipelineConfig, which in turn is the configuration class for OnlineFeaturePipeline.

Instead of taking the options for the parts of the feature pipeline directly, it reads in the names of configuration classes. I'm conflicted about whether this is a wise thing to do, but I think for ease of scripting it's probably better to do it like this.
