Simplify zuul_console port binding logic

Now that osic-cloud1 is providing IPv6 only, we need to update
zuul_console to also include ipv6 support.  Previously, our logic
would only bind to 1 address, even if the host supported both
ipv4/ipv6.

With help from fungi, we can simplify our logic binding to both ipv4
and ipv6 at the same time.
