Minor spec file cleanupminor_spec_cleanup

- Use require_relative in all the specs vs. expanding on the current file
path.
- Add missing license headers
- Don't silently swallow ipaddr_extensions not being installed. Make it
  a development dep instead
- Remove a rescue on ipaddress as we only do this in one place and it's
  a required gem
- Make the Openstack plugin spec setup the same way as every other spec
