Public bug reported:

Please see this thread:

http://lists.openstack.org/pipermail/openstack-
dev/2017-August/121097.html

The instances index page in Admin dashboard generates a request for
Glance every time Server.image_name() is called (the method is called a
lot when building the page). Project dashboard  doesn't have this issue
because it retrieves all images objects first and sets each instance's
image attribute to corresponding image object.

>From what I searched in commit log, the support in Project dash board
was introduced in bd6bad5f. df194c8b (integrated early this year)
patched Admin dashboard's index page to retrieve image objects but
didn't set instances' image attribute to corresponding image object.

BTW, it's not clear in Glance API doc if user with admin role can get
all project images (including project private ones) when issuing "GET
/v2/images" reqeust, but my experiments verified it can.
