    Api-ref: add a warning to execute_resize endpoint

    In the API reference, we'd better to provide more information
    about the execute_resize API endpoint:
    https://developer.openstack.org/api-ref/application-container/#resize-tty-when-execute-command-in-a-container
    This endpoint is not designed for end-users. It is designed
    for UI or CLI to adjust the TTY's size of a command
    execution in a container. Consider documenting this
    with a warning message (as what we did for the resize
    endpoint: https://developer.openstack.org/api-ref/application-container/#resize-a-container).
