DESCRIPTION:
    This sample demonstrates how to start a training job for a Conversation Authoring project (async)
    and print the final training result.
USAGE:
    python sample_train_async.py

REQUIRED ENV VARS (for AAD / DefaultAzureCredential):
    AZURE_CONVERSATIONS_AUTHORING_ENDPOINT
    AZURE_CLIENT_ID
    AZURE_TENANT_ID
    AZURE_CLIENT_SECRET

NOTE:
    If you want to use AzureKeyCredential instead, set:
      - AZURE_CONVERSATIONS_AUTHORING_ENDPOINT
      - AZURE_CONVERSATIONS_AUTHORING_KEY

OPTIONAL ENV VARS:
    PROJECT_NAME  # defaults to "<project-name>"
