Steps to reproduce

1. Cisco equipment details
   Cisco IOS XR Software, Version 6.5.3
   Version : 6.5.3

2. Relevant Cisco equipment configuration

3. send telegraf output to influxdb

Expected behavior

Expected to convert child class name and child policy name to tags ,
expected to get all class names related to child class name but we receive only "class default"

Actual behavior

convert only class name for parent policy not child and hence get only all class names for parent not child policy .
