    Introduced the OpenAPIConnector component, enabling direct invocation of REST endpoints as specified in an OpenAPI specification.
    This component is designed for direct REST endpoint invocation without LLM-generated payloads, users needs
    to pass the run parameters explicitly.

    Example:
    ```python
    from haystack.utils import Secret
    from haystack.components.connectors.openapi import OpenAPIConnector

    connector = OpenAPIConnector(
        openapi_spec="https://bit.ly/serperdev_openapi",
        credentials=Secret.from_env_var("SERPERDEV_API_KEY"),
    )
    response = connector.run(
        operation_id="search",
        parameters={"q": "Who was Nikola Tesla?"}
    )
    ```
