instance launching broken when using nova-api generated imageRefs through osapi

[Anthony Young]

When attempting to launch a server through the OSAPI, I get the following error when trying to launch the image http://myhost:8774/v1.1/images/3:

curl -v -X 'POST' http://myhost:8774/v1.1/servers -H 'Content-Type: application/json' -H 'X-Auth-Token: mytoken' -d '{"server": {"flavorRef": "http://myhost:8774/v1.1/flavors/2", "name": "testing server creation", "imageRef": "http://myhost:8774/v1.1/images/3"}}'

{"badRequest": {"message": "Cannot find requested image http://myhost:8774/v1.1/images/3: 'images'", "code": 400}}

The error is that nova attempts to retrieve images/detail by talking to itself over port 8774 rather than by talking to glance directly over port 5000. Instead, nova should be talking to glance using default parameters.
