[Automation] ConfigDescription for ScriptedTrigger is missing

[philippwaller]

According to the implementation of the ScriptedAutomationManager, a ScriptedTrigger can be created in a similar way as a ScriptedCondition or ScriptedAction:

// GROOVY 2.5.7 
// 1. Step: create private handler
// 2. Step: register handler and cache privId
// 3. Step: pass the privId to the module configuration

// 1. create private handler
SimpleTriggerHandler handler = new SimpleTriggerHandler() {
    void setRuleEngineCallback(Trigger module, SimpleTriggerHandlerCallback ruleCallback) {
        super.setRuleEngineCallback(module, ruleCallback)
        // custom handler entry point 
     }
}

// 2. register private handler
String privId = automationManager.addPrivateTriggerHandler(handler)

// 3. create module
TriggerBuilder.create()
    .withId("custom_trigger")
    .withTypeUID("jsr223.ScriptedTrigger")
    .withConfiguration(new Configuration(['privId': privId]))
    .build()

However, the PrivateScriptesTypes definition for jsr223.ScriptedTrigger does not mentioned the required input parameter privId. But since the shown procedure works perfectly, I guess the configDescription is just missing.
