Description
This allows the controller to handle the case where the externalview is missing a segment that is in the ideal state. I'm not sure yet how this happens in our cluster, but it keeps the whole controller table UI from loading which makes it hard to even identify the missing segment. There's likely room to either
I want to say this is related to #7779, but we've seen it in clusters without tiered storage as well.
To test, locally I ran the realtime quickstart, deleted the segment from externalview, and opened the page in the UI. The segment now reports as BAD
and has no server
