Introduce cluster support for TypeDB 3.x, featuring server replicas and the new version message. Remove database replicas. Instead, add server replicas (by extending the usual `Server` message) with a similar set of fields. Instead of adding a `is_primary` flag, introduce an extensible enum `ReplicaType` for more granular split between primary and supporting nodes. To reduce the network overhead, this new information is provided in the initial server's connection response.
Split the protocol into 3 services: * TypeDBService (contains common TypeDB logic): server, database, user, and transaction management, etc. * TypeDBClusteringService (contains TypeDB logic regarding clustering): replica registration, server status. * RaftService (contains Raft logic): replication operations. Split the old RaftPeeringService into TypeDBClusteringService and RaftService. Move separate services and their implementation files into separate subpackages. Rename methods. Introduce `ServersGet` method for single server status retrieval. Introduce `registration` method to verify the replica registration operation before submitting it to Raft.
Add protobuf schema for Raft's 'state mutation request'. The schema defines how the data is transported over the network and stored in the Raft log. - Add a protobuf definition for State Mutation Request - Create a mock RPC endpoint to handle that message as a hack to get the code generator to work
…nd optionalize Server message

Release notes: usage and product changes
Reorganize Raft service's request messages to mirror the structure of TypeDB service's methods. Additionally, optionalize the Server message to allow returning pure Raft Agent id without other server information available for Clustered operations (in case the replica is not available).
Implementation
I just did it!
