DESCRIPTION:
    This sample shows how to get metrics for a test run

USAGE:
    python get_metrics.py

    Set the environment variables with your own values before running the sample:
    1)  AZURE_CLIENT_ID - client id
    2)  AZURE_CLIENT_SECRET - client secret
    3)  AZURE_TENANT_ID - tenant id for your Azure
    4)  LOADTESTSERVICE_ENDPOINT - Data Plane endpoint for Loadtestservice
