There is a chance to see this error when write data to hudi with flink, and
slot number per TM is larger than 1.
java.lang.IllegalArgumentException: A metric named
hudi_table1.lock.acquire.duration already exists
The cause is in constructor of HoodieLockMetrics, when different thread from
different slot of a Flink TM new HoodieLockMetrics, timer of identical
metricName may registered to
MetricRegistry multiple time, causing this error.

we can add synchronized statement in function 'createTimerForMetrics' to make
the test and set action atomic to avoid adding a timer multiple times.
