> In {{AsyncProcess.SingleServerRequestRunnable}}, it seems we update serverStatistics
twice.
> The first one is that we wrapper {{RetryingCallable}}  by {{StatsTrackingRpcRetryingCaller}},
and do serverStatistics update when we call {{callWithRetries}} and {{callWithoutRetries}}.
Relates code like below:
> {code}
>   @Override
>   public T callWithRetries(RetryingCallable<T> callable, int callTimeout)
>       throws IOException, RuntimeException {
>     T result = delegate.callWithRetries(callable, callTimeout);
>     return updateStatsAndUnwrap(result, callable);
>   }
>   @Override
>   public T callWithoutRetries(RetryingCallable<T> callable, int callTimeout)
>       throws IOException, RuntimeException {
>     T result = delegate.callWithRetries(callable, callTimeout);
>     return updateStatsAndUnwrap(result, callable);
>   }
> {code}
> The secondary one is after we get response, in {{receiveMultiAction}}, we do update again.

> {code}
> // update the stats about the region, if its a user table. We don't want to slow down
> // updates to meta tables, especially from internal updates (master, etc).
> if (AsyncProcess.this.connection.getStatisticsTracker() != null) {
>   result = ResultStatsUtil.updateStats(result,
>   AsyncProcess.this.connection.getStatisticsTracker(), server, regionName);
> }
> {code}
> It seems that {{StatsTrackingRpcRetryingCaller}} is NOT necessary,  remove it?
