Replicate Key-Value storage

Each key in key-value storage is only saved in single node in current version, it should be replicate at least 2 nodes. It is better to configurable how many node it is replicated.

May be it is affected to bellow parts:

- [ ] Set destinations and how to determine that set is success (now version is only single flag acked)
- [ ] Sub destinations and how to determine that sub is success (now version is only single flag acked)
- [ ] Sync destinations
- [ ] Get destinations

May be the simplest way (any ack mean success) is the best in decentralized environments; because if it not success that time, it will be synced after that.

A issue menciona a replicação do armazenamento de chave-valor entre nós. Analise o storage module para entender a lógica atual de single-node. Identifique as funções para set, sub, sync e get destinations. A alteração envolve modificar a acknowledgment logic e adicionar replication factors configuráveis. Verifique os testes existentes para storage operations para ver como o sucesso é determinado atualmente.
