[KAFKA-4468] Correctly calculate the window end timestamp after read from
state stores
I have decided to use the following approach to fixing this bug:
1) Since the Window Size in WindowedDeserializer was originally unknown, I
have initialized
a field _windowSize_ and created a constructor to allow it to be
instantiated
2) The default size for __windowSize__ is _Long.MAX_VALUE_. If that is the
case, then the
deserialize method will return an Unlimited Window, or else will return
Timed one.
3) Temperature Demo was modified to demonstrate how to use this new
constructor, given
that the window size is known.
