conf: Rename life cycle actions to event actions

While current on_{poweroff,reboot,crash} action configuration is about
configuring life cycle actions, they can all be considered events and
actions that need to be done on a particular event. Let's generalize the
code by renaming life cycle actions to event actions so that it can be
reused later for non-lifecycle events.
