Fix Ironic configuration for IPv6

When using IPv6 for provisioning baremtal nodes ironic.conf
needs:
  - [pxe]/ip_version must be set to '6'. Add parameter
    IronicIpVersion.
  - [deploy]/http_url must have the IPv6 address wrapped.
    Use the $NETWORK_uri value from hiera which carries
    an ip address fit for use in url.
