Create an Openstack Compute client.
Use ServiceClient and pagination in Flavor operations.
Ditto for Images.

I'm guessing that the images service also uses marker-and-limit pagination. I'll have to
check when I'm less :airplane:.
Use clients and pagination for Servers, too.

Whew.
Rename ListResult(s) to ListPage.
The server test passes again.
Implement images.Get(). Image tests now pass.
Move compute acceptance tests into a v2 folder.

Consistency!
