--------------------------------------------------------------
[~martijnvisser] this PR upgrades Flink from Kryo v2.x to Kryo v5.x and
preserves backward compatibility with existing savepoints and checkpoints:
[https://github.com/apache/flink/pull/22660]
This keeps the Kryo v2 project dependency for backwards compatibility only and
otherwise uses Kryo v5.x.

> Key: FLINK-3154
> URL: https://issues.apache.org/jira/browse/FLINK-3154
> Project: Flink
> Issue Type: Improvement
> Components: API / Type Serialization System
> Affects Versions: 1.0.0
> Reporter: Maximilian Michels
> Priority: Not a Priority
> Labels: pull-request-available
>
> Flink's Kryo version is outdated and could be updated to a newer version,
> e.g. kryo-3.0.3.
> From ML: we cannot bumping the Kryo version easily - the serialization format
> changed (that's why they have a new major version), which would render all
> Flink savepoints and checkpoints incompatible.
