This patch set includes a function that uses a resource pool InstanceID to determine the
resource type. SDC has been updated to use this function instead of using the ref's
ResourceType attribute (which might not be available).
Updates from original patchset:
Was using device_type_from_classname(), which is intended to get the resource type from
Device instance classnames. It doesn't properly support resource pool InstanceIDs.

Adding a function that returns resource type based on poolid.
The following function takes a string (the resource pool's InstanceID) and parses it
to determine the corresponding resource type.

Fix SDC - AllocationCapabilities - RASD returns error.
Querying SDC using an AllocationCapabilities instance returns: "Could not get
ResourceType". This is because SDC is expecting the AC ref to have the ResourceType
defined. But ResourceType isn't a key, so SDC can be queried without specifying a
value for ResourceType.
Instead of using the ResourceType attribute, get the resource type from the InstanceID.
Failing query:
wbemcli ai -ac Xen_SettingsDefineCapabilities
'http://localhost:5988/root/virt:Xen_AllocationCapabilities.InstanceID="ProcessorPool/0"'
