task: Added Release Plan Template events (#8668)

As part of the release plan template work. This PR adds the three events
for actions with the templates.

Actually activating milestones should probably trigger existing
FeatureStrategyAdd events when adding and FeatureStrategyRemove when
changing milestones.
