when user disabled core dns i see hosts-file configmap does not get deleted.

Always

1. Enable core dns using the /etc/microshift/config.yaml file
2. Restart microshift service.
3. Now user can see that there is a configmap with name called hosts-file that gets created in the openshift-dns namespace.
4. Now disable the core dns using the /etc/microshift/config.yaml file by setting the status to Disabled.
5. Restart microshift

I can see that hosts-file configmap that gets created with core dns enablement does not get deleted when it is disabled.

When core dns is disabled hosts-file configmap should be deleted as well.
