Stephan Ewen updated FLINK-19047:
---------------------------------
    Description: 
All ResultPartitions have the unaligned checkpointing methods, but some do not 
support checkpoints and throw an {{UnsupportedOperationException}}.

I suggest to follow the idea of interface segregation to put the methods 
relating to unaligned checkpoints in a dedicated interface.

> Move unaligned checkpoint methods from ResultPartition to separate interface.
