A no-op instrumenter that executes blocks without publishing any notifications. Useful for disabling instrumentation on specific connections or components.

This is stateless and thread-safe, so a single instance can be shared.

ActiveSupport::Notifications.null_instrumenter.instrument("sql.active_record") do
  # executes without any notification overhead
end
