Check OperandRegistry when checking no-op operators

[Daniel-Fan]

Found an issue when doing a fresh install CPFS in simple topology.

CS operator is trying to check if OperandRegistry has any no-op operator requested before cleaning any NSS resources. However, OperandRegistry is not present yet in fresh installation.

After the update, CS operator will check if OperandRegistry CRD exists or not. If it is not there, it will skip the no-op operator check, and continue NSS cleanup.
