> In order to avoid a tangled web of if/else statements around every possible permutation of config.yml and an equally complicated validation routine, we need to utilize a versioning strategy that allows for specific parsing and validation code for each version of the ConfigSchema.
> This will allow us to determine if a schema will be compatible with an older MiNiFi instance more easily by validating the structure of the file at a given version while still supporting an upconvert on read to the latest ConfigSchema while parsing at runtime.
> It should also facilitate a deprecation strategy of removing older versions' classes without needing to touch current implementation
