[Feature Request] Make NoOpResult visible to overridden engine implementations #19949
Description
Is your feature request related to a problem? Please describe
Engine interface in OpenSearch provides an abstract method NoOpResult noOp(NoOp noOp) to allow custom implementations. However, the NoOpResult class constructors are package-private, and hence implementations cannot reuse the NoOpResult class.
Describe the solution you'd like
Update the NoOpResult class constructors to be public.
