/*
We make an attempt here to identify the events that take place during
lifecycle of the apiserver.

We also identify each event with a name so we can refer to it.

Events:
- ShutdownInitiated: KILL signal received
- AfterShutdownDelayDuration: shutdown delay duration has passed
- InFlightRequestsDrained: all in flight request(s) have been drained
- HasBeenReady is signaled when the readyz endpoint succeeds for the first time
