Add support to send connectivity logs from g_wlan_logging thread. Add new HOST_LOG_DRIVER_CONNECTIVITY_MSG event flag which wakes up the gwlan_logging thread when set. Also register connection manager callbacks to send the logging event. Check if logging queue is empty whenever the gwlan_logging thread is woken up and send the logs to userspace if the count doesn't exceed the allowed threshold.
