FYI protip, you can add the following to a custom environment file to
configure this value (as we don't expose the config by default)

parameters_defaults:
  ControllerExtraConfig:
    nova::config::nova_config:
      placement/randomize_allocation_candidates:
        value: true


And then do a deployment.  This will persist it and ensure future
scaling/management updates won't remove this configuration.
