* - queryable: Whether the field is queryable via QueryInterface.
* Defaults to TRUE if 'computed' is FALSE or not set, to FALSE otherwise.
* - translatable: Whether the field is translatable. Defaults to FALSE.
* - configurable: A boolean indicating whether the field is configurable
* via field.module. Defaults to FALSE.
* - property_constraints: An array of constraint arrays applying to the
* field item properties, keyed by property name. E.g. the following
* validates the value property to have a maximum length of 128:
* @code
* array(
* 'value' => array('Length' => array('max' => 128)),
