Description

add a metric to indicate whether rollback has occurred in final compaction state to warn people check flink job.

currently, when flink job start async compaction on a mor table, the metrics in org.apache.hudi.metrics.FlinkCompactionMetrics 
will update including pendingCompactionCount,compactionDelay,compactionCost.

However, when a compaction failed need a metric to
tell user a specific instant whether the final compaction has occured rollback.

so attemp to add a metric named compactionFailedState in org.apache.hudi.sink.compact.CompactionCommitSink to record the instance
happend rollback, which also means the current compaction failed in current time
