[RN] `dsc` should not delete CheCluster namespace if it is `openshift-operators`

= dsc server:delete --delete-namespace might remove other Operators Before this update, `dsc server:delete --delete-namespace` deleted any namespace in which the {prod-short} instance had been installed, even the `openshift-operators` namespace if inadvertently chosen during installation. Removal of the `openshift-operators` namespace might result in unintended removal of other installed Operators. With this update, the `dsc server:delete` command with the `--delete-namespace` option does not remove the `openshift-operators` namespace. NOTE: The default namespace for {prod-short} is `openshift-devspaces`. The `dsc` CLI tool installs {prod-short} in the correct namespace by default. To correctly install {prod-short} in the OpenShift web console, see the link: https://access.redhat.com/documentation/en-us/red_hat_openshift_dev_spaces/3.3/html-single/administration_guide/index#installing-devspaces-on-openshift-using-the-web-console [administration guide].
