This change is based upon a toy project I have at https://github.com/Molter73/config-much. The basic idea is to use the reflection API from protobuf to populate the runtime configuration structures, which should allow us to add new fields to our protobuf definitions and have them magically show up in our code to use.

Description
This change is based upon a toy project I have at https://github.com/Molter73/config-much.
The basic idea is to use the introspection and reflection APIs from protobuf to populate the runtime configuration structures, which should allow us to add new fields to our protobuf definitions and have them magically show up in our code to use.
This is an alternative implementation to #1993.
