Review comment:
Looks like `InputProcessorUtil` also belongs to `checkpointing` as it's
sole purpose is to create `CheckpointedInputGate`. And the purpose of the
latter is to handle events, mostly checkpoint barriers.
How about moving it too along with `UpstreamRecoveryTracker`/Impl and
`CheckpointedInputGate`?
WDYT @pnowojski , @AHeise ?
