Based on scylladb#24 from @chiragb1994. Introduce support for postImages. Since postImages and preImages have the same read-before-write cost, users interested in both events should now benefit from them. The only missing piece is to actually wire the postImage under its actual message Envelope. This shouldn't be particularly hard, but is outside the scope of this commit and series.

I have added an option to stream only the
postimageevents to Kafka.Use case: I have enabled
preimage(full) on my table andpostimage(true). Thepostimageevent is created in CDC table but not streamed to Kafka. This event is needed (the latest state of the row) to be able to stream it into a different database.Relates to issue: #8
