Improve gossip scalability * The previous bottleneck was the size of the Status message. The limit was around 2000 top level entries. Now it can handle 100000 top level entries without problems. * Split the Status message into chunks * Remove compression of the Status message, since that did not reduce the size much

Commit:de7b944
Author:Patrik Nordwall
Committer:Patrik Nordwall

Performance improvements * LazyDigest, to avoid serialization for digest until needed * periodic notification of subscribers * gossip sendBack * send to limited number of nodes from aggregators * protobuf and serialization optimizations

Commit:3c3254a
Author:Patrik Nordwall

Remove local seqNo * It does not provide the safetey that was intended * The seqNo must be used as in the ReplicatedShoppingCartSpec example, i.e. get-modify-update cycle with stashing in-between, and that is too complicated and too easy to get wrong * Disabled RemovedNodePruning for now
