Menu callback; Creates the form for configuration of a single action.

We provide the "Description" field. The rest of the form is provided by the action. We then provide the Save button. Because we are combining unknown form elements with the action configuration form, we use an 'actions_' prefix on our elements.

Parameters

$action: Hash of an action ID or an integer. If it is a hash, we are creating a new instance. If it is an integer, we are editing an existing instance.

Return value

A form definition.
