Emulab portal won't instantiate experiment using an image whose access was explicitly granted via `grantimage`
I had a classic experiment that used
FBSD92-STD, but we recently rescinded global access to that image. So the (converted) experiment failed to instantiate via the portal saying the experiment would not run on any cluster. That is fine, it would not even run via the classic interface.
So I used
grantimage to explicitly allow the testbed project to use that image. Now it would swap in via the classic interface, but still not via the portal.
