[FLINK-8451] [serializers] Make Scala tuple serializer deserialization more
failure tolerant
## What is the purpose of the change
Scala tuples (and thus also case classes) classes are serialized together
with their serializers. The `serialVersionUID` changed from Scala 2.10 to 2.11.
We need to ignore those changes when reading a serializer config snapshot.
## Brief change log
- Make deserialization more failure tolerant
## Verifying this change
- See `org.apache.flink.api.scala.runtime.TupleSerializerCompatibilityTest`
## Does this pull request potentially affect one of the following parts:
- Dependencies (does it add or upgrade a dependency): no
- The public API, i.e., is any changed class annotated with
`@Public(Evolving)`: no
- The serializers: yes
- The runtime per-record code paths (performance sensitive): no
- Anything that affects deployment or recovery: JobManager (and its
components), Checkpointing, Yarn/Mesos, ZooKeeper: no
- The S3 file system connector: no
## Documentation
