> When operators are not added into CoreOperatorType enum, they are displayed on Web UI as UNKNOWN_OPERATOR.
> Screenshots:
> now -> unknown_operator.JPG
> should be -> maprdb_sub_scan.JPG
> Though plugins work fine without this changes, it's still would be nice to display operator type on Web UI.
> But dependency on protobuf enum removes the ability for format plugins to truly be drop-in pluggable.
> In this case as option we may need to refactor this interface to just return a String and not use the protobuf enum, or have a separate "notes" field if we want to have a generic filescan operator ID in this enum with extra data to say what kind of scan we used.
