[FLINK-8500] [Kafka Connector] Get the timestamp of the Kafka message from
kafka consumer
## What is the purpose of the change
This pull request make the Kafka timestamp and timestampType available in
the message deserialisation so one can use it in the business logic processing.
## Brief change log
- Introduced new interface `KeyedWithTimestampDeserializationSchema` with
extra parameters in the `deserialize` method.
- Added the `KeyedWithTimestampDeserializationSchemaWrapper` class to keep
the code backwards compatible.
- Adjusted the Kafka Connectors 0.10+ to support the new interface too.
- Adjusted the Kafka Connectors 0.9- to 'hide' this new interface since
these version of Kafka don';t support timestamps
- Added some documentation.
