Mark query answer accessors as allocating for SWIG

[dmitrii-ubskii]

Usage and product changes

We mark query_answer_into_rows and query_answer_into_documents as creating a new allocation that needs to be freed by SWIG. Previously, the iterators extracted from the QueryAnswer would have been ignored by SWIG and not deallocated when the wrapper is freed.

Implementation

Mark query_answer_into_rows and query_answer_into_documents as %newobject and %delobject.

Trivial Change

• This change is trivial and does not require a code or architecture review.

Code

• Packages, classes, and methods have a single domain of responsibility.
• Packages, classes, and methods are grouped into cohesive and consistent domain model.
• The code is canonical and the minimum required to achieve the goal.
• Modules, libraries, and APIs are easy to use, robust (foolproof and not errorprone), and tested.
• Logic and naming has clear narrative that communicates the accurate intent and responsibility of each module (e.g. method, class, etc.).
• The code is algorithmically efficient and scalable for the whole application.

Architecture

• Any required refactoring is completed, and the architecture does not introduce technical debt incidentally.
• Any required build and release automations are updated and/or implemented.
• Any new components follows a consistent style with respect to the pre-existing codebase.
• The architecture intuitively reflects the application domain, and is easy to understand.
• The architecture has a well-defined hierarchy of encapsulated components.
• The architecture is extensible and scalable.
