Until we handle bridges non-destructively, only manage bridges created by NM. When quitting write out a file listing all bridges created by NM and a timestamp, and when starting read that file and if the timestamp is within 30 minutes, manage any bridge that was listed in that file. This scheme, while not foolproof (eg, if NM crashes), should ensure that NM can recognize bridges it created if it's restarted. The file is stored in /run or /var/run, which is cleaned each restart, ensuring that the state does not persist across reboots. If an automatic or user-initiated activation request for a bridge NM does not manage is received, that request is denied. Only if the bridge interface does not yet exist, or was present in the managed bridges file, will an NMDeviceBridge be created and activation be possible.
