* Updates the instrumentation_server service to use mux instead of the builtin router, and have it store the router in the module server: this is so we can register the /ring endpoint to check the status of the ring * Create a new Ring service that depends on the instrumentation server and declares it as a dependency for the storage server * Create standalone MemberlistKV service for Ring service to use * Update the storage server Search and GetStats handler to distribute requests if applicable
