Add support for --help flag in core

Passing the `--help` flag should cause the application to print a document to the console describing the way the configuration system was wired together. This work **MUST** be done prior to wiring any modules, so additional logs will not be emitted

This command will:
- iterate through each project going into the application
- print out a list of all configuration properties
- name, description, type, module level default value, value enum, required state
- environment variable / `--switch` that can be used to define the value

A related flag should also be introduced to just dump the data as json, for processing by other scripts
