Summary:
The motivation is that some metrics are flaky and we don't want to fail the trial just because we encountered one exception fetching. Especially trials with
period_of_new_data_after_trial_completion()
> 0.This alternative to implementing this on the metric is that the set of recoverable errors should be a scheduler option, and it's more a matter of scheduler use case than metric.
