[backport-1.1] [FLINK-5942] [checkpoint] Harden ZooKeeperStateHandleStore
to handle corrupt data
Backport of #3447 onto `release-1.1` branch.
If calling ZooKeeperStateHandleStore.getAll or getAllSortedByName as the
ZooKeeperCompletedCheckpointStore does in the recovery case, the operation
will fail
if there exists a Znode with corrupted data. This will break Flink's
recovery
mechanism, because it will read this node over and over again. In order to
solve this
problem, this commit changes the behaviour such that it ignores corrupted
Znodes it
cannot read.
