[FR] setting loglevel through nsconfig

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?

Start by tracing how nsconfig values are read by the iOS run command and how the existing loglevel setting is applied. Verify whether configuration can suppress the noisy device logs without hiding JavaScript logs, then confirm the behavior on a device and simulator.
