      Description of problem:

          When user projects monitoring feature is turned off the operator is cleaning up resources for user project monitoring, running multiple delete requests to apiserver.
This has several drawbacks:
* API Server can't cache DELETE requests, so it has to request etcd every time
* Audit log is flooded with "delete failed: object 'foo' not found" record

The function should first check that the object exists (GET requests are cachable) before issuing a DELETE request

      Version-Release number of selected component (if applicable):

          4.16.0

      How reproducible:

          Always

      Steps to Reproduce:

          1. Start 4.16.0
    2. Check audit log
    3.

      Actual results:

          Audit log has messages like:
configmaps "serving-certs-ca-bundle" not found
servicemonitors.monitoring.coreos.com "thanos-ruler" not found

printed every few minutes

      Expected results:

          No failed delete requests
