Add test cases to install / uninstall modules for cloud, aws_cloud, k8s and openstack

@yas, I have the following comments about this patch.

   Does this function need a try/catch block?

   aws_cloud_config js library has been removed. I don't know if this attach is needed anymore.

   K8s and OpenStack should have an update function that updates the default icon.

   `field termination` should be `field_launch_resources`

@yas, thank you for the updated patch. It looks good to me now.
