Summary: As discussed in Ax/Botorch sync. mark_trial_early_stopped signuture is brought in line with other mark_trial_STATUS methods and BaseTrial now validates that data must be present on a trial when marking it early stopped. This Exception from BaseTrial is a ValueError to stay in line with convention in that module, but is wrapped in an Ax UnsupportedError in Client where we expect exceptions to be Ax classes.
