> This leak can be triggered by running the skupper-router http1 unit test for a single router, example:
> /usr/bin/python3.10 "/home/kgiusti/work/skupper/skupper-router/BUILD/tests/run.py" "-m" "unittest" "-v" "system_tests_http1_adaptor.Http1AdaptorOneRouterTest.test_001_get"
>  
> The leak occurs when skupper-router is attempting to connect to a remote HTTP server via a raw connection but shuts down before any raw connection events are processed (e.g. No PN_RAW_CONNECTION_CONNECTED or _DISCONNECTED).
> During shutdown the router frees the proactor and expects any outstanding raw connection resources owned by it to be freed.
> I've traced the proactor shutdown logic, and when the leak occurs there is a final call to praw_connection_cleanup() for the outstanding connection, but the praw_connection_t still holds a pointer to the allocated addrinfo.  praw_connection_cleanup() frees the praw_connection_t but does not call freeaddrinfo(prc->addrinfo) to release the addrinfo memory.
