DESCRIPTION:
    This sample demonstrates how to perform CRUD operations on agent Sessions
    using the asynchronous AIProjectClient.

    Sessions only work with Hosted Agents.

USAGE:
    python sample_sessions_crud_async.py

    Before running the sample:

    pip install "azure-ai-projects>=2.3.0" python-dotenv aiohttp

    Set these environment variables with your own values:
    1) FOUNDRY_PROJECT_ENDPOINT - The Azure AI Project endpoint, as found in the Overview
    2) FOUNDRY_MODEL_NAME - The deployment name of the AI model.
    3) FOUNDRY_HOSTED_AGENT_NAME - Optional. The Hosted Agent name. Defaults to
        `MyHostedAgent`.

SDK FUNCTIONS:
    - project_client.agents.create_version_from_code: creates a temporary hosted agent version.
    - project_client.agents.create_session: creates a session for the agent.
    - project_client.agents.get_session: retrieves a session by ID.
    - project_client.agents.list_sessions: lists sessions for an agent.
    - project_client.agents.delete_session: deletes a session by ID.
