/**
 * Gets attribute value by name from the storage entity and returns it as a boolean. Most types of boolean strings are supported (e.g. true/false, on/off,
 * yes/no, etc.).
 *
 * @param attributeName the attribute name (case insensitive)
 * @param storageEntity the storage entity
 * @param attributeRequired specifies whether the attribute is mandatory (i.e. whether it has a value or not).
 * @param attributeValueRequiredIfExists specifies whether the attribute value is mandatory (i.e. the attribute must exist and its value must also contain a
 * value).

 * @return the attribute value from the attribute with the attribute name as a boolean. If no value is configured and the attribute isn't required, then
 *         false is returned.
 * @throws IllegalStateException if an invalid storage attribute boolean value was configured.
