port nova v2 images related tests into nova v3 part2

In nova v3 api, there is no image api. So in nova v3
api tests, we just keep these tests related to create_image
action of the server api. Other tests are moved into glance
testing, also some tests is no longer available, as some
actions are just nova v2 api for glance proxy behaviour.
eg: update the specified item of image properties. In glance
we can only  update all values of image properties.

Partially implements blueprint nova-v3-api-tests
