Add Rust Log Service Memberlist to Chroma System Database Management

This PR introduces a new Kubernetes Custom Resource (CR) and corresponding RBAC configuration for managing a memberlist specific to the Rust log service within the Chroma cluster. The sysdb service is updated to create and manage the Rust log service memberlist via its configuration, wiring, and CLI flag handling. Supporting changes update the Helm chart version and expand the Tiltfile to ensure deployment orchestration incorporates the new resource.

Key Changes:
• Adds a new Kubernetes MemberList CR for the Rust log service, alongside ClusterRole and ClusterRoleBinding definitions for both sysdb and rust-frontend-service.
• Augments sysdb server configuration and CLI options to accept Rust log service memberlist parameters (name/pod label) and initializes its management in the system database's GRPC server.
• Enhances the sysdb server initialization workflow to properly create, error-check, and start the memberlist manager for the log service.
• Helm chart bumped to v0.1.40; Tiltfile includes the new memberlist resource for dev environments.

Affected Areas:
• Kubernetes Helm templates (distributed-chroma)
• Sysdb server configuration and initialization logic (go/pkg/sysdb/grpc/server.go)
• Sysdb CLI flags (go/cmd/coordinator/cmd.go)
• Tiltfile/dev environment setup
