Feature request: add 'trigger optimizers' button to collection info

[timvisee]

In Qdrant 1.9 and 1.10 we're adding a grey collection status. It means a collection still needs to do optimizations, but it is currently not happening. Instead, it is waiting for any update operation to actually trigger these optimizations.

This normally happens if a Qdrant node is restarted while optimizations were ongoing. On restart it will not restart optimizations right away to prevent crash loops. A user needs to trigger them explicitly as described above.

I think it would be nice to add a button for triggering optimizations in the collection info panel. It would help users resolve this situation. The button would be shown when the collection status is grey, a bit like:

That button could send a very simple update request, like we've described in our documentation here: https://qdrant.tech/documentation/concepts/collections/#grey-collection-status

I mentioned it is part of Qdrant 1.9 and 1.10. In our current release it'll show some intermediate message, while the grey collection status will only appear from Qdrant 1.10 onward. Just showing the button in 1.10 if status == "grey" is probably good enough, so it'll start appearing in our next release.
