cf412bc81e
Adds functionality for dual stack capabilities and automatic population to neutron with the correct response based upon the IP version of the provisioning/cleaning/rescue or tenant ports. This was origianlly intended to be separated from removing the need for [pxe]ip_version, however the resulting code changes from doing both this and making ironic support dual stacks touched the same tests and some of the same code, so combined is simpler.
