Delete with empty name results in deletecollection

[jpbetz]

What happened (please include outputs or screenshots):

According to kubernetes/kubernetes#127746, if delete is called with an empty name, the client will not fail but instead call delete on the collection resource and delete the entire collection of resources.

What you expected to happen:

Delete either performs the delete of a single resource, or fails.

How to reproduce it (as minimally and precisely as possible):

Call delete, but provide an empty name.

The delete method compose the request to something like api/v1/namespaces/{namespace}/pods/{name} and when name is empty, it becomes api/v1/namespaces/{namespace}/pods, which by Kubernetes definition will delete all resources in the namespace / cluster.

This was also reported in #2209

I think at this point it will be hard to change this behavior, because we don't know how many users may already depend on this behavior.

What would the client code from python look like to make this call? Is there already a separate deletecollection call?
