Ok, let me jot some thoughts donw on this so we have it....

 * All monitoring should be done async, without polling. Ie. using signals and callback, not sleep(5); check_drives();
 * I think we can use gio.VolumeMonitor() to listen for connect/disconnect of volumes. Then we use gio.Volume.get_uuid() as the key in the 'storage' table.
 * I have not checked NetworkManager or ConnMan, but I am pretty sure that both provide some DBus API to get async  notifications when the connection goes away and comes up. We should use the key 'inet' to store the connectivity state in the 'storage' table.
 * All online subjects requiring a connection to be available, should have their storage attribute set to 'inet'

Bug description:
This is a reminder bug.

We need to write a "storage monitor" that manage the various storage mediums we can have event subjects stored on. The storage monitor should write any changes back to the 'storage' table in the DB.

What we need to track is connection and disconnections of storage volumes (probably using gio) - ie. track whether or not files on USB thumb drives are available or not etc.  Also the network connection state should be updated in the storage table so that we can filter out remote files and website on request.
