Enable qos templates in Harvest

[rahulguptajss]

1. We are going to create a custom.yaml file in the appropriate directory. In below commands, Harvest is installed in /opt/harvest

• For ZapiPerf vi /opt/harvest/conf/zapiperf/custom.yaml
• For RestPerf (9.12+ onwards) vi /opt/harvest/conf/restperf/custom.yaml

2. Add below content in this file. If custom.yaml already exists then just add the template under Objects:

objects:
  Workload:               workload.yaml
  WorkloadDetail:         workload_detail.yaml
  WorkloadVolume:         workload_volume.yaml
  WorkloadDetailVolume:   workload_detail_volume.yaml

3. Restart Harvest
4. Wait for few minutes(at least 10 min) and you should see qos metrics in prometheus.
