    [FLINK-9923][tests] Harden OneInputStreamTaskTest#testWatermarkMetrics

    ## What is the purpose of the change
    
    Convert the WatermarkGauge's field currentWatermark from long to AtomicLong because
    writes and reads can happen from different threads. Unfortunately, we cannot simply
    make it volatile because not all JVM support atomic writes to longs.
    
    cc @zentol.
