CLOUD: Change the cloud icon to be updated by the main thread

The cloud manager registers itself as an event source as a mean to be polled
periodically by the GUI or engine code. The periodical polling is used to
update the OSD icon indicating background sync activity.

Also move the cloud icon from ConnectionManager to CloudManager,
allowing to decouple icon handling from network connections updates.
