    The items listed can be used with `slcli order place` to specify

    Package keynames can be retrieved using `slcli order package-list`

    \b
    Note:
        Items with a numbered category, like disk0 or gpu0, can be included
        multiple times in an order to match how many of the item you want to order.

    \b
    Example:
        # List all items in the VSI package
        slcli order item-list CLOUD_SERVER

    The --keyword option is used to filter items by name.

    The --category option is used to filter items by category.

    Both --keyword and --category can be used together.

    Example:
        # List Ubuntu OSes from the os category of the Bare Metal package
        slcli order item-list BARE_METAL_SERVER --category os --keyword ubuntu
