FILE: sample_publish_events_to_a_topic_using_sas_credential.py
DESCRIPTION:
    These samples demonstrate sending an EventGrid Event using a shared access signature for authentication.
USAGE:
    python sample_publish_events_to_a_topic_using_sas_credential.py
    Set the environment variables with your own values before running the sample:
    1) EVENTGRID_SAS - The shared access signature to use Event Grid. This is typically given to you
    after creating it using the `generate_sas` method.
    2) EG_TOPIC_HOSTNAME - The topic hostname. Typically it exists in the format
    "https://<YOUR-TOPIC-NAME>.<REGION-NAME>.eventgrid.azure.net/api/events".
