Main/ExtPackManager+CloudProviderManager+VirtualBox: Handle runtime install and uninstall of extension packs containing cloud providers. This is a safeguard against uninstalling active cloud providers (which would cause crashes), and makes the install more convcenient. At the same time it eliminated the need to have a special "detect all cloud providers" logic when VBoxSVC is started. It achieves perfect singleton property of the per-extpack CloudProviderManager and the related CloudProvider objects. Nothing is ever created twice (which would cause trouble with coordinating e.g. the profile file updates).
