feat(cluster): implement distributed clustering with etcd coordination

- Integrate etcd-client for distributed coordination and leader election - Add remote client macros with proper formatting for all services - Implement RequestMetrics for tracking RPC performance and errors - Add rate limiting mechanism across all service endpoints - Create ElectionRequest and ElectionResult message types for leader election - Add role management with primary/replica switching capabilities - Implement health checker with automatic failover detection - Add repository count metrics for cluster monitoring - Update Cargo.toml with etcd-client and dashmap dependencies - Modify RepoEntry to include read_only flag for replica handling - Implement should_accept_election logic to prevent duplicate elections - Add RoleChangedEvent handling for cluster role updates
