[jira] [Commented] (FLINK-7440) Add eager serializable checks on
provided de-/serialization schemas for Kinesis consumer / producer
[ https://issues.apache.org/jira/browse/FLINK-7440?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16125341#comment-16125341 ]

[FLINK-7440] [kinesis] Add various eager serializability checks on to Kinesis connector
## What is the purpose of the change
This is a minor improvement for user experience for the Kinesis consumer and producer.
If the provided `KinesisDeserializationSchema`, `KinesisSerializationSchema`, `KinesisPartitioner` is not serializable, a more clear error message is shown instead of some vague "the implementation of RichSunkFunction is not serializable".
## Brief change log
Changes are broken up into 2 commits:
- for consumer: eagerly check serializability of `KinesisDeserializationSchema`, with better error msgs
- for producer: eagerly check serializability of `KinesisSerializationSchema` and `KinesisPartitioner`, with better error msgs.
## Verifying this change
Added new tests to both `FlinkKinesisConsumerTest` and `FlinkKinesisProducer` test, to verify that the expected error message is thrown (and also not thrown if the provided arg instances are serializable). Also included tests to check that `FlinkKinesisConsumer` and `FlinkKinesisProducer` themselves are serializable.
