[OHAI-518] remove *.static.cloud-ips.com

Fixes issues with Pull Request #215
- fixes tests
- moves `require "resolve"` to top of file
So my english was weird, but the concern is if this stub covers the `it "should create rackspace"` test which is up in the shared_examples, so we're thinking we need a stub for resolv at the top scoping level, up around line 21 of this file.
