Description of problem:

Compute resources are good, but the definition of "delete" should be configurable. Many enterprise customers don't delete VM disk images when they delete the VM container. They age out the disk images after the fact.
However, when you delete a VM with Foreman, and that VM is tied to a VMware compute resource, Foreman will tell VMware to delete the on disk image as well.

Can we allow users to configure the compute resource to keep the disk images instead of deleting them?

It's just too easy to completely delete a VM from the Foreman console.

Even having a warning dialog when you delete to let people know that the VM including the disk image is being deleted, and not just disassociated from the Foreman.

Ideally you have to type the full name of the VM if you want to delete the disk too.
