    Add boolean parameter `NovaSchedulerPlacementAggregateRequiredForTenants`
    which allows to set `scheduler/placement_aggregate_required_for_tenants`
    parameter. It controls whether or not a tenant with no aggregate affinity
    will be allowed to schedule to any available node.
    If aggregates are used to limit some tenants but not all, then this should
    be False. If all tenants should be confined via aggregate, then this
    should be True.
    Default value for NovaSchedulerPlacementAggregateRequiredForTenants is false.
