Fix shared module loading

* Moving function add_query_module from CMakeLists from tests/e2e/magic_functions to tests/e2e

* Adding failing test copying behavior when loading c module (.so) into memgraph.

* Fixing issue where NO_ERROR status returned  MgpTransAddFixedResult was converted to false

* Removing unnecessary transformation

* removing incorrect parameterization of test

* re-adding parametrized transformation

+ * Communication server.
+ *
+ * Listens for incoming connections on the server port and assigns them to the
+ * connection listener. The listener and session are implemented using asio
+ * async model. Currently the implemented model is thread per core model
+ * opposed to io_context per core. The reasoning for opting for the former model
+ * is the robustness to the multiple resource demanding queries that can be split
+ * across multiple threads, and then a single thread would not block io_context,
+ * unlike in the latter model where it is possible that thread that accepts
+ * request is being blocked by demanding query.
+ * All logic is contained within handlers that are being dispatched
+ * on a single strand per session. The only exception is write which is
+ * synchronous since the nature of the clients conenction is synchronous as
+ * well.
+ *
+ * Current Server architecture:
+ * incoming connection -> server -> listener -> session
+
+ *
+ * @tparam TSession the server can handle different Sessions, each session
+ *         represents a different protocol so the same network infrastructure
+ *         can be used for handling different protocols
+ * @tparam TSessionData the class with objects that will be forwarded to the
+ *         session
