Nelson Torres ed6a3bda39 Refine history gap/termination signalling ... Namely handling backends which do not provide a default "frame size-duration" in their init-config by making the backfiller guess the value based on the first frame received. Deats, - adjust `start_backfill()` to take a more explicit `def_frame_duration: Duration` expected to be unpacked from any backend hist init-config by the `tsdb_backfill()` caller which now also computes a value from the first received frame when the config section isn't provided. - in `start_backfill()` we now always expect the `def_frame_duration` input and always decrement the query range by this value whenever a `NoData` is raised by the provider-backend paired with an explicit `log.warning()` about the handling. - also relay any `DataUnavailable.args[0]` message from the provider in the handler. - repair "gap reporting" which checks for expected frame duration vs. that received with much better humanized logging on the missing segment using `pendulum.Interval/Duration.in_words()` output.		2025-01-29 23:24:33 +00:00
