##### SUMMARY

Two vmware modules uses `copy()` to duplicate an internal instance of a pyvmomi object. This to be able to modify the object during an iteration.

- https://github.com/ansible/ansible/blob/622a493ae03bd5e5cf517d336fc426e9d12208c7/lib/ansible/modules/cloud/vmware/vmware_datastore_facts.py#L220

As explain here, https://github.com/ansible/ansible/pull/60196/files#r312643761 this is not the best approach and this may impact the performance.
