The current executeServerScanImmediately() method will scan for all server Resource types, and the current executeServiceScanImmediately() will scan all server Resources for services. In a number of scenarios, we need to refresh only a certain server Resource type (e.g. when a patch has been applied to a server Resource and we need to update its version) or only the services below a certain server Resource (e.g. when a patch has been applied to a server Resource and we need to update its child Resources' versions, or when a server Resource's plugin config has been changed and we need to rescan it for child services). In these cases, for efficiency/performance sake, we should provide new methods in InventoryManager for scanning only what is necessary and use those methods instead.
