Review comment:
do agree for better code readability moving the verification code to a
separate method makes sense, but did not quite understand `We cannot assume
that this is the last segment to be deleted`. `SegmentOp` implemented based on
your design that it will be called multiple times during upgrade/downgrade, but
whenever it's called it will be for 1 segment. Let me know if my understanding
is not correct.
Also, Segment in any of these states `ONLINE, CONSUMING, ERROR, OFFLINE` is
considered not deleted?
