Since it is possible to script the configuration of EC2 clouds using groovy, it would be very useful to implement the functionality to delete/modify existing clouds. In the example provided here: https://github.com/jenkinsci/ec2-plugin

It shows how to add a configuration using jenkins.clouds.add() method, however no method is specified for deleting/modifying existing clouds. In the scenario where you one wants to scripts this entire configuration, and the configuration changes over time, this is essential. 

I am unsure if this functionality needs to be implemented in jenkins core or if it is possible through the plugin, so apologies if the labelling is off.
