#942 Improve scope break down process
OpenGnsys has a hierarchical scope system to organize clients: +------+ |Center| +------+ | | | | v v +--------------------+ +----------+ +-->+Groups of classrooms+----->+Classrooms| | +-+------------------+ +----------+ | | | | +-----+ | | v v +-----------------+ +-------+ +-->+Groups of clients+--------->+Clients| | +-+---------------+ +-------+ | | +-----+ OpenGnsys can send commands and tasks to several clients simultaneously selecting a scope. For example: send poweroff to center Faculty of Pharmacy. We had a waterfall process to loop through all members of the scope and obtain the clients. This commit simplifies the process with queries that save us to loop through the members. Co-authored-by: Irina Gómez <irinagomez@us.es>
