"Delete dependent objects of this resource" might cause confusions

Cause: The web console shows a pre-selected "Delete dependent objects of this resource" checkbox when deleting a Deployment, or many other resources. Users expected that deleting a Deployment removes all resources that the web console created when using the "Import from Git" or "Import image container" flow. But other resources like the created ImageStream, Route, Service and Secrets wasn't deleted. The checkbox only deletes resources that are linked with metadata.ownerReferences field. See https://kubernetes.io/docs/concepts/overview/working-with-objects/owners-dependents/ Consequence: Users are confused that the web console doesn't delete everything. And a new import via "Import from Git" or "Import image container" (with the same name) fails because of these leftover resources with an error "ImageStream with that name already exists". Fix: When deleting a Deployment the web console now shows a second pre-selected option "Delete other resources created by console". If the user kept this checkbox enabled all mentioned resources above are automatically deleted. Result: The web console now cleanup resources it creates and allows the user to reimport the same application with the same name again.
