A response through this extension can have many servers and making one query per server can slow down response time dramatically. This change switches the extension to use one DB query instead of many queries. It also avoids queries when the key is already populated, such as when the results include responses from a remote zone. This change reduces a 'nova list' of 21 servers from 14 seconds to 1 second on my (relatively slow) development system. Change-Id: I8476dbca0f87ff2a3d69bd7b8f51c296e41e3388
