[FR] setting loglevel through nsconfig

Inizia tracciando il modo in cui i valori di nsconfig vengono letti da iOS run command e il modo in cui viene applicata l'impostazione loglevel esistente. Verifica se la configurazione può sopprimere i log rumorosi del dispositivo senza nascondere i log JavaScript, quindi conferma il comportamento su un dispositivo e sul simulatore.

I have an issue with the ios run and logging level.
When i run it on my device (need to check on the simulator but i think it is the same) i see a lot of "polluting" logs which makes it almost impossible to see the JS logs:

I think i actually see all the device logs.
Could we have a way to set the loglevel through nsconfig? Would it filter those?
