Add HA benchmark Summary: A simple benchmark that starts a HA cluster with 3 machines. The benchmark issues only `CREATE (:Node)` queries.

Add log compaction for Raft, pt. 1 Summary: In this part of log compaction for raft, I've implemented snapshooting and snapshot recovery. I've also refactored the code a bit, so `RaftServer` now has a pointer to the `GraphDb` and it can do some things by itself. Log compaction requires some further work. Since snapshooting isn't synchronous between peers, and each peer can work at their own pace, once we've compacted the log so that the next log to be sent to peer `x` isn't available anymore, we need to send the snapshot over the wire. This means that the next part will contain the `InstallSnapshotRPC` and then maybe one more that will implement the logic of sending `LogEntry` or the whole snapshot.
