API server should return 202 if the operation is asynchronous #33196
Description
Code 202 means "The request has been accepted for processing, but the processing has not been completed".
In k8s, the DELETE operation is asynchronous in two cases: 1. a graceful deletion of pod. 2. the object has pending finalizers. In both cases the object remains in the key-value store after the API server responds. The API server should return 202 in such cases. I haven't evaluated if such a change is backward compatible.
