shill: Add a ModemInfo object that's a peer of DeviceInfo.
ModemInfo is responsible for managing ModemManager instances. Each ModemManager
instance watches for and handles an individual ModemManager DBus service. Each
ModemManager will be responsible for creating cellular devices associated with
that ModemManager.
