Delete segments of a given time range

There are occasional asks from users to delete segments of a given range. (.e.g from 4days ago to yesterday). Since the segment metadata has the range info, it's possible for such deletion at the day's level for offline tables.

No files, tests, or entry points are named. Start by tracing how offline-table segment metadata records time ranges and how existing segment deletion is initiated; define completion as supporting deletion of segments whose ranges fall within a requested day-level time range.
