Method modified

src/adapter/src/config/params.rs:68–85

Return a vector of [ModifiedParameter] instances that need to be pushed to the backend and reset this set to the empty set for future calls. The set will start growing again as soon as we modify a parameter from the `synchronized` set with a [SynchronizedParameters::modify] call.
