[FLINK-6025] [core] Add Flink's own JavaSerializer for Kryo serialization
This commit adds a reimplemented JavaSerializer to be registered with
Kryo. This is due to a know issue with Kryo's JavaSerializer that may
use the wrong classloader for deserialzation.
Instead of registering Kryo's JavaSerializer for Throwables, it is now
changed to register the reimplemented JavaSerializer. Users who bump
into ClassNotFoundExceptions if they are using Kryo's JavaSerializer for
their own types are also recommended to change to Flink's
JavaSerializer.
