[backport] [FLINK-5285] Abort checkpoint only once in BarrierTracker
Backport of #2963 for the release-1.1 branch.
Prevent an interleaved sequence of cancellation markers for two consecutive
checkpoints
to trigger a flood of cancellation markers for down stream operators. This
is done by
aborting each checkpoint only once and don't re-create checkpoint barrier
counts for already
aborted checkpoints.
