Feature request description

Currently the dora plugin supports sending deployment events, but not failure events.

Right now if you want to send a failure event, you must use the API, and that is a shame when such a easy to use tool already exists.

Solution

1. Add new interface here, FailureEvent
2. Add new failture.ts here
3. Add new failture.test.ts here
4. Add new sendFailureEvent here and here
5. Reword message strings here to use "DORA event" instead of "DORA deployment event"
