 Currently, changes in configuration are handled quite ad-hoc; for 'basic'
 items such as strings or numbers, this is not much of a problem, as they
 are either changed or not. But for lists and maps, it would be better to
 have specific diffs (values added, removed, updated). Right now when a
 list item is changed, the whole list is considered to be modified (for
 instance when you add a listen_on port).

 This may end up being more than one ticket worth of effort, in which case
 it'll become a meta-ticket. It may also be part of a bigger effort (as
 discussed in the april 2012 F2F) to change how configuration works.
 Depending on the work we end up creating for that, this ticket should be
 included (or, if this is included by other ticket(s) for that work,
 invalidated).
