This commit replaces the ChangeSet with a simpler bool based change model that can be directly used in the map builder to build the appropriate map response based on the change that has occured. Previously, we fell back to sending full maps for a lot of changes as that was consider "the safe" thing to do to ensure no updates were missed. This was slightly problematic as a node that already has a list of peers will only do full replacement of the peers if the list is non-empty, meaning that it was not possible to remove all nodes (if for example policy changed). Now we will keep track of last seen nodes, so we can send remove ids, but also we are much smarter on how we send smaller, partial maps when needed.
