Description

Would be nice to be able to subscribe to events (alarms) as well as data values. Generally speaking, you subscribe to OPC UA Events similarly to data changes, but by using monitoring parameters that contain an event filter instead of data change filter. Besides the DataChangeFilter property, the UAMonitoringParameters class also has an EventFilter property (of UAEventFilter type).

Contributor guide

Research direction
Familiarize yourself with the existing OPC UA input plugin in Telegraf, then add event subscription support using the EventFilter property of UAMonitoringParameters. Look at how the plugin currently monitors data changes and extend it to monitor events.
