Some operator settings can be applied dynamically in a configmap instead of requiring the operator to restart. While these settings may be infrequently updated, applying these settings in the configmap can avoid an unnecessary operator restart. This will also make the operator deployment more consistent with the non-helm install. Signed-off-by: Travis Nielsen <tnielsen@redhat.com>
