DESCRIPTION:
    Given an AIProjectClient, this sample demonstrates how to use the asynchronous
    `.datasets` methods to upload files, create Datasets that reference those files,
    list Datasets and delete Datasets.

USAGE:
    python sample_datasets_async.py

    Before running the sample:

    pip install azure-ai-projects azure-identity aiohttp

    Set these environment variables with your own values:
    1) PROJECT_ENDPOINT - Required. The Azure AI Project endpoint, as found in the overview page of your
       Azure AI Foundry project.
    2) CONNECTION_NAME - Required. The name of the Azure Storage Account connection to use for uploading files.
    3) DATASET_NAME - Optional. The name of the Dataset to create and use in this sample.
    4) DATASET_VERSION_1 - Optional. The first version of the Dataset to create and use in this sample.
    5) DATASET_VERSION_2 - Optional. The second version of the Dataset to create and use in this sample.
    6) DATA_FOLDER - Optional. The folder path where the data files for upload are located.
