Make PathChildrenCache ignore old versions
Currently, PathChildrenCache, when set to cache data, can potentially cache
stale versions of files. In some client code, we are seeing CHILD_UPDATE
events being delivered with out-of-order versions.
This PR is for a fix to the logic for what to do with old `Stat` objects.
That said, I looked over the unit tests and wasn't able to come up with a great
strategy for verifying this behavior. It would be nice to be able to mock
something out so that I just feed out-of-order events to the method in
question, but I'm not seeing that injection point. Any ideas on how this could
be easily UT'd?
