Feature request: "End of Lifecycle Event" log messages

[mpdude]

I am using log collection/processing software to monitor the CodeDeploy agent logs and spot errors during the deployment process.

Sometimes it is hard to tell if a particular Lifecycle Event has been processed successfully: When looking for strings that indicate failure, you cannot tell for sure if they did not occur or if the event is still running some time-consuming task and thus you need to keep on watching.

So, the feature request is as simple as: For every Lifecycle Event, write out a distinct log line like "End of LifecycleEvent" + the event name. This should happen under all conditions – successful runs of the hook scripts, failures, aborts etc.

This Feature request was also raised in #220 . Adding this here for visibility.
