As the type is called NMPacRunnerManager, the proper name for the
functions is nm_pac_runner_manager*(). Alternatively, it the type
should be NMPacrunnerManager.
nm_pacrunner_manager_send() would only fail if passed in a NULL proxy_config.
And then it would log a <info> message without details about what failed.
Just don't do that.
A new object NMPacRunnerManager has been added to manage and interact
PacRunner. It invokes both DBus methods on PacRunner DBus interface.
It stores the returned object path from CreateProxyConfiguration()
to feed as parameter to DestroyProxyCofiguration() when network goes down.
