Bug 1784678

Description of problem:
This is on UPI on baremetal openstack OCP 4.2.12 staging cluster.  After deploying Node Feature Discovery (NFD) operator from OperatorHub from the OCP console, and creating an instance of that operator, NFD gets deployed successfully and the nfd pods in the openshift-nfd namespace are created successfully.  All the nodes get the NFD specific labels.

After letting the cluster sit for several hours, at least 6-8 hours or overnight, the openshift-nfd namespace disappeared along with the all the nfd pods.

The NFD operator shows still installed and the operator pod in the namespace I created is still running.

Version-Release number of selected component (if applicable):
Server Version: 4.2.12
Kubernetes Version: v1.14.6+32dc4a0


How reproducible:
Seen twice

Steps to Reproduce:
1. UPI baremetal cluster install of OCP 4.2.12 on openstack, 3 master and 3 worker nodes
2. from OCP console, logged in as kubeadmin user with kuebadmin-password, create a new project called test-nfd.
3. From Console Operators -> Operator Hub:  Search for "NFD", and click on Node Feature Discovery operator icon, then install.  Choose: 
- install in namespace you created 
- 4.2 for update channel
- Approval strategy:  Automatic
4. Create instance of that operator

Actual results:
NFD operator is deployed successfully in test-nfd namespace and is running.  A new namespace called "openshift-nfd" is created along with the nfd-master and nfd-worker worker for each node.  NFD labels are created successfully on all node.  Only problem is after several hours (6-8 hours), the namespace "openshift-nfd" along with all the nfd pods disappears.

$  oc get pods -n openshift-nfd
No resources found.

Expected results:
Openshift-nfd namespace should not disappear and the nfd master and worker pods in that namespace should not disappear either and stay running.

$  oc get pods -n openshift-nfd
