This pull request introduces a new consumption mode for Kinesis with Enhanced FanOut support. What this lets us do is provide a dedicated consumption pipe for Bento instead of depending on shared polling.
As much as possible I have tried to re-use the existing Kinesis input architectures and have only added EFO in terms of consuming the events but checkpointing + batching have been left identical. Quite a lot of the logical patterns have also been copied from the polling implementation and then altered to support EFO.
