Tekton Trigger
TriggerTemplate: 创建资源的模板(比如用来创建 PipelineResource 和 PipelineRun)；
TriggerBinding: 校验事件，提取负载字段；
EventListener: 连接TriggerBinding和TriggerTemplate到可寻址的端点(事件接收器)。使用从各个TriggerBinding中提取的参数来创建TriggerTemplate中指定的 resources. 同样通过interceptor字段来指定外部服务来对事件负载进行预处理；
ClusterTriggerBinding: cluster级别的TriggerBinding。
