Description Jiří Mencák 2020-02-11 16:16:48 UTC 
Description of problem:
NTO does not remove profiles for nodes which were removed from the cluster.

Version-Release number of selected component (if applicable):
Any 4.4 release.

How reproducible:
Always

Steps to Reproduce:
1. Install OCP
2. oc get nodes
3. oc get profiles -n openshift-cluster-node-tuning-operator # There should 1 profile per node.
4. Delete one worker node.
5. The tuned profile should be removed too, but is not.

Actual results:
The tuned profile not removed on node deletion.


Expected results:
The tuned profile removed on node deletion.
