Review Comment:
Also, `DELETE_BATCH_FAILED_SIZE` already seems correct.
Here, in both if and else blocks, we have same value (4) being asserted for
`DELETE_BATCH_FAILED_SIZE`.
> MUTATION_BATCH_FAILED_SIZE metric is incorrectly updated for failing delete

> Key: PHOENIX-5980
> URL: https://issues.apache.org/jira/browse/PHOENIX-5980
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.15.0
> Reporter: Chinmay Kulkarni
> Assignee: Aman Poonia
> Priority: Major
> Labels: metrics, phoenix-hardening, quality-improvement
> Fix For: 4.17.0, 4.16.2
>
>
> In the conn.commit() path, we get the number of mutations that failed to be
> committed in the catch block of MutationState.sendMutations() (see
> [here|https://github.com/apache/phoenix/blob/dcc88af8acc2ba8df10d2e9d498ab3646fdf0a78/phoenix-core/src/main/java/org/apache/phoenix/execute/MutationState.java#L1195-L1198]).
>
> In case of delete mutations, the uncommittedStatementIndexes.length always
> resolves to 1 and we always update the metric value by 1 in this case, even
> though the actual mutation list corresponds to multiple DELETE mutations
> which failed. In case of upserts, using unCommittedStatementIndexes.length is
> fine since each upsert query corresponds to 1 Put. We should fix the logic
> for deletes/mixed delete + upsert mutation batch failures.
> This wrong value is propagated to global client metrics as well as
> MutationMetricQueue metrics.
