[FLINK-5214] Clean up checkpoint data in case of a failing checkpoint
operation
Adds exception handling to the stream operators for the snapshotState
method. A failing
snapshot operation will trigger the clean up of all so far generated state
resources.
This will avoid that in case of a failing snapshot operation resources
(e.g. files) are
left behind.

Add StateSnapshotContextSynchronousImplTest
Add AbstractStreamOperator failing snapshot tests
