metabaseSegmentKey` TransferQueueItem We are unifying which name (and type) we are using for value we are using to point to segment. We want to use `key` instead of `path`. Dedicated type `metabase.SegmentKey` was created for this purposes also. This change is doing refactoring around gracefulexit. Change-Id: I90d51ff087b206179e61d5f1bc95f4709d76f917
