A defaultKey can be used for commonly used configuration objects like AutonumberConfig
that are expected to be mapped to a specific key, like autonumbering without requiring
the user to remember these keys.
val config: Config = ???
val res: ConfigResult[AutonumberConfig] = config.get[AutonumberConfig]
In the example above retrieval happens solely based on the type of the result
with the associated key being specified by an implicit DefaultKey.
