[JCLOUDS-357] ComputeService.listnodes() in the case of softlayer cloud takes about 2 minutes for cloud with only 3 machines

Description

The significant delay is on the following call: method apply(VirtualGuest) of
org.jclouds.softlayer.compute.functions.VirtualGuestToNodeMetadata
findLocationForVirtualGuest.apply(from).
If I removes in above calling initializing location within builder then it improves performance dramatically: instead of 2 minutes it takes now about 12 seconds in order to bring 3 nodes..
Performance is improved as well if in addition to location the following fields of builder are not initialized: operatingSystem, hardware, group.
I think initializing of of these builder fields should be optional, since like in my case I need only id, hostname, public IP and private ip.
I'm aware that next calls will go to cache and will have much better performance, but I need good performance already during first call.
