[Cloud Provider] - Detecting when a user deletes a cloud configuration

[Robert Smith]

Please forgive me if this is an FAQ - my searches didn't turn up anything.

I'm working on a new Cloud Provider plugin, and for the life of me, I can't figure out how to trigger code based upon a user deleting a cloud config in the Jenkins UI. I don't see any likely methods in the classes associated with Cloud, nor do I see any kind of "GlobalConfigChangeListener". 

Any advice would be welcomed!

Cheers,

Robert

I do not think you can. Nor would we want to add such a listener,
since an admin using `configuration-as-code` might for example just
delete a block of YAML and restart Jenkins. Reconsider why you think
you needed this to begin with.

My use case is pretty simple. If a user deletes an instance of my cloud provider in the UI, I want to do the needed cleanup - terminate any agents associated with that instance of the cloud provider, deregister it from our server, etc. I suppose that I can poll for the change on a timer, it just seems that it would be more efficient to be notified of the deletion.
