Description

This issue tracks the removal of the deprecated/legacy interfaces that are still in the code and can only be removed once the move to the new Flink 1.2 checkpointing is completely in place.

So far, these are StreamCheckpointedOperator and the legacy snapshot methods on the testing harnesses. Furthermore, codepaths and classes touching legacy state (e.g. StateAssignmentOperation or TaskStateHandles can be cleaned up.
