Review Comment:
just a general FYI that we're aiming for making all `MetricsReporter` instances fully `Serializable` as part of https://github.com/apache/iceberg/pull/7370. So would be good to consider this here as well.

Review Comment:
typically the expectation of a `MetricsReporter` is that it doesn't throw when `report` is called as otherwise it would interfere with scans/commits.
For example, the `RESTMetricsReporter` exits early if the `report` ever turns out to be null (which technically shouldn't happen) and executes all operations in a `try-catch`
