Support backends for online dynamic configurations

[mdedetrich]

Is there any plan on the roadmap to support online dynamic configurations (stuff like zookeeper/consul/aws config).

Understand that this can be out of scope for the ficus, but it seems like a natural fit (especially if you have an application that uses static configuration in files like application.conf but you then want to move onto dynamic configurations where you don't need to restart your application to apply new configs)

IIRC, Typesafe config supports loading config from remote urls. I do think that the management of remote config and the auto-reloading of the application is out of the scope of ficus.
