Actual results:
1. more events are available here http://pastebin.test.redhat.com/735562
It looks like we print duplicate messages A & B, even they have 1 second duration


Expected results:
1. Show necessary events only once

Additional info:
Not sure if this is console operator issue or openshift/library-go/pkg/operator/events issue, please help re-direct if it's considered as a bug
