Support for Distributed Log

[2hamed]

For this library to be fully Raft compatible, support for a distributed log should be added.

A rough explanation of the Log Replication procedure is described in this Wikipedia page.

First, we need to come up with a format to store logs. Each log entry describes an arbitrary command for which all nodes should commit to their state machines.
Upon receiving a request, the leader node notifies all follower nodes, and once the log entry is confirmed each should commit that request to their log storage.
