> We should be exposing whether a mutation has failed through our metrics
> system. This should be done both within global and request level metrics.
> The task basically boils down to:
> 1) Adding a new enum MUTATION_BATCH_FAILED_COUNTER in MetricType.
> 2) Adding a new enum GLOBAL_MUTATION_BATCH_FAILED_COUNTER in
> GlobalClientMetrics
> 3) Adding a new CombinableMetric member called mutationBatchFailed to
> MutationMetric class
> 4) Making sure that the two metrics are updated within the catch exception
> block of MutationState#send()
> 5) Unit test in PhoenixMetricsIT
