[Upsert] Skip removing upsert metadata when shutting down the server

[Jackie-Jiang]

When the server shuts down, removing all the metadata from the upsert manager can be time consuming and not provide any value since we re-construct the metadata during restart. This PR tracks whether the upsert manager is closed, and skips the segment remove if it is already closed
