    Pass victim context for provider on BF abort

    This change is needed for custom provider implementations to
    have a way to access the victim in the application context.

    Helper interface operation_context to pass caller context for
    service/provider callbacks in more type safe way.

    Fix provider loading in test for release builds

commit 6df17812d9
Author: Denis Protivensky <denis.protivensky@galeracluster.com>
Date:   Tue Dec 14 20:28:56 2021 +0300

    Introduce set_provider_factory() method for server_state

    This allows injecting an application allocated provider into
    server_state.

    After this virtual provider getter is unnecessary. Made the getter
    normal method and fixed unit tests accordingly.
