Issue XD-1181: Surface the provenance of a default to the user
When using @Value for providing a default value in a module options POJO, make it so that the REST API (and hence the module info command) advertises that 1) the expression was ${foo.something} 2) to the best extent possible (value may come from another property source), tell which config file it came from (introspecting the @PropertySource annotation)
