function RulesDataUI::renderOptionsLabel

Renders the value with a label if an options list is available.

Used for data UI classes implementing the RulesDataDirectInputFormInterface.

In case an options list is available, the usual render() method won't be invoked, instead the selected entry is rendered via this method.

@todo for Drupal 8: Refactor to avoid implementations have to care about option lists when generating the form, but not when rendering values.
