docs: Verifies an order with the given package and prices.
  
          This function takes in parameters needed for an order and verifies the order
          to ensure the given items are compatible with the given package.
  
          :param str package_keyname: The keyname for the package being ordered
          :param str location: The datacenter location string for ordering (Ex: DALLAS13)
          :param list item_keynames: The list of item keyname strings to order. To see list of
                                     possible keynames for a package, use list_items()
                                     (or `slcli order item-list`)
          :param str complex_type: The complex type to send with the order. Typically begins
                                   with `SoftLayer_Container_Product_Order_`.
          :param bool hourly: If true, uses hourly billing, otherwise uses monthly billing
          :param string preset_keyname: If needed, specifies a preset to use for that package.
                                        To see a list of possible keynames for a package, use
                                        list_preset() (or `slcli order preset-list`)
          :param dict extras: The extra data for the order in dictionary format.
                              Example: A VSI order requires hostname and domain to be set, so
                              extras will look like the following:
                              'virtualGuests': [{'hostname': 'test', 'domain': 'softlayer.com'}]}
          :param int quantity: The number of resources to order
