FILE: sample_create_delete_table_async.py

DESCRIPTION:
    These samples demonstrate creating and deleting individual tables from the
    TableServiceClient and TableClient

USAGE:
    python sample_create_client_async.py

    Set the environment variables with your own values before running the sample:
    1) AZURE_STORAGE_CONNECTION_STRING - the connection string to your storage account
    2) AZURE_STORAGE_ENDPOINT_SUFFIX - the Table service account URL
    3) AZURE_STORAGE_ACCOUNT_NAME - the name of the storage account
    4) AZURE_STORAGE_ACCESS_KEY - the storage account access key
