DESCRIPTION:
    This sample demonstrates how to get, create, update, or delete an alias with an existing index.
USAGE:
    python sample_index_alias_crud_operations.py

    Set the environment variables with your own values before running the sample:
    1) AZURE_SEARCH_SERVICE_ENDPOINT - the endpoint of your Azure Cognitive Search service
    2) AZURE_SEARCH_API_KEY - your search API key
    3) AZURE_SEARCH_INDEX_NAME - the name of your search index (e.g. "hotels-sample-index")
