Expose the application configuration with information about the source

I am a member of an organization which actively uses dropwizard to develop its services. I have to say it is a really nice framework, carefuly thought out, a pleasure to use. I have recently started out with a task an I found a feature in dropwizard which IMHO is missing. I would like to be able to print out the configuration which was used to start the application along with what is the source of the configuration parameter. I’d like to see something like this in the startup log of the application:

Starting application ${APPLICATION_NAME}
Configuration parameters passed to the application:
    server.applicationConnectors.[0].type = "http"           default
    server.applicationConnectors.[0].port = "9100"          json/yaml
    server.adminConnectors.[0].type = "http"                   default
    server.adminConnectors.[0].port = 9101                    jvm param
.
.
.

I would be more than glad implementing this, but I’d need first of all your acceptance on the whole idea. Of course some pointers/directions are more than welcome.

@ryankennedy I like your proposal with Google Docs and some POC code, so I created a very short document, describing some hows, whens, whats which describe some of ideas from this issue with some proposals how to address them.

Everyone with the link to the document should be able to comment - and I’m open for any feedback.
