[Feature]: Configuring the logging level

Is your feature request related to a problem?

Dashboard generates a large number of logs, many of which are useless. For example: 00:39:13 WARNING - get swap memory failed: The operation completed successfully.: this counter has not data 00:39:15 WARNING - get swap memory failed: The operation completed successfully.: this counter has not data 00:39:17 WARNING - get swap memory failed: The operation completed successfully.: this counter has not data And so it goes, round the clock.

Not all servers for 3x-ui are enterprise-grade machines. Many of them are ordinary old laptops and nettops with 16–32 GB SSDs. Logs are eating up old disks, yet a dashboard isn't really necessary for personal use.

Describe the solution you'd like

The log level should be configurable not only for display in the dashboard but also for writing to a file. It would be ideal if the recording of the system state could be disabled completely.

Alternatives you've considered
