For the new implementation of this method, we probably should handle type
casting exceptions, and wrap them as `IllegalArgumentException`s. Since we're
doing the property config validating locally, this really shouldn't happen, but
it would be good to add handling type cast errors here to make this class
self-contained.

> Project: Flink
> Issue Type: New Feature
> Components: Kinesis Connector
> Reporter: Tzu-Li (Gordon) Tai
> Assignee: Wei-Che Wei
> Fix For: 1.2.0
>
>
> We had a Kinesis user requesting this feature on an offline chat.
> To be specific, we let all initial Kinesis shards be iterated starting from
> records at the given timestamp.
> The AWS Java SDK we're using already provides API for this, so we can add
> this functionality with fairly low overhead:
