[client-connection] add an auto-close property for ClientConnection
The next commit introduce a connect function that open a new Session and return
an associated ClientConnection. The Session should not be used by anything else
than the created ClientConnection, so we want to close it at the same time than
the ClientConnection. The implementation in this changeset is simplistic. We
probably want to move this notion in the session itself. This be improved once
we have server side Connection
