On removeItemAndWait investigate if an error should be thrown

[cmwylie19]

Describe what should be investigated or refactored

When we do the JSON Patch to the Kube CP, if we are attempting to patch against an item that does not exist, we are throwing catching the 422 that comes back from the api-server. We should investigate if this is the best approach.

Specifically look into swallowing the 422 on the removeItem/removeItemAndWait to keep things idempotent
