    Switch total_resources to use stack_count_total_resources

    This change uses database queries to count the total number of
    resources in a nested stack tree instead of loading every stack
    and every resource in that stack.

    This should result in a significant improvement in memory use
    for stacks with many nested stacks and resources.
