feat: impl ControlService for rudder

[MrCroxx]

Introduce ControlService in rudder for cluster control (e.g. AddWheels, AddKeyRanges).

Changes:

• Introduce ControlService in rudder for cluster control (e.g. AddWheels, AddKeyRanges).
• Refactor AddWheels(AddEndpoints originally) and AddKeyRanges, make rudder responsible for handling requests and broadcast changes to wheels.
• Refactor bench.
• IMPORTANT: Temporarily disable integrations tests. Enable them after runkv client can redirect requests to raft leader.
