Why I did it

For any platform which supports the asic_sensors pulling, it requires the configuration files (config_db#.json) contain the following configuration to trigger the system to poll the ASIC sensors temperature. Fixes https://github.com/Nokia-ION/ndk/issues/48
Adding Yang model support to fixes #20633

• Microsoft ADO (number only):

How I did it

• Add new module src/sonic-config-engine/asic_sensors_config.py with function get_asic_sensors_config(). This function checks if device data platform.json contains the following configuration, it will generate the asic_sensors pulling configuration.

$ cat platform.json
{
...
...
...
   "asic_sensors": {
        "poll_interval": "10",
        "poll_admin_status": "enable"
    }
}

• Modify the script sonic-cfggen platform option "-H" to call the function get_asic_sensor_config() to generate the asic_sensors pulling configuration.
• Added new UT test_asic_sensors_config() to test_cfggen.py to test related the implementation.

Notice: For all platforms which support the asic_sensors polling requires to add the following definition to the device data platform.json file

$ cat platform.json
{
...
...
...
   "asic_sensors": {
        "poll_interval": "10",
        "poll_admin_status": "enable"
    }
}

Also add Yang Model support the ASIC_SENSORS configuration. INcluding YangModel UT.

How to verify it

1. Running the new image on the platform which supports the ASIC_SENSORS
2. Execute the CLI command "sonic-cfggen -H --print-data", the following code will be generated

{
   "ASIC_SENSORS": {
        "ASIC_SENSORS_POLLER_INTERVAL": {
            "interval": "10"
        },
        "ASIC_SENSORS_POLLER_STATUS": {
            "admin_status": "enable"
        }
    }
}
