[Bug]: Issue with Disabling Logs in Netdata

[vmusaely]

Bug description

I attempted to follow the instructions outlined in the Netdata documentation to disable logs (Documentation Link) but encountered an issue where logs are still being printed.

Expected behavior

After making the configuration changes and restarting the Netdata service, I expected the logs to be disabled completely.

Steps to reproduce

1. Navigate to the Netdata configuration directory.
2. Open the netdata.conf file in a text editor.
3. Locate the [logs] section within the configuration file.
4. Set the following options as per the documentation:
   [logs]
   daemon = none
   facility = daemon
   access = none
   debug = none
   level = emergency
   collector = none
   health = none
   error = none
5. Save and close the netdata.conf file.
6. Restart the Netdata service.

Installation method

docker

level = emergency

Both python.d and go.d didn't respect emergency, alert and critical levels - fixed in #17587.

Disabling a source by setting "source = none/off" doesn't work. We need to fix it.
