Subject: [PATCH] Listen on both IPv4 and IPv6 by default

We use `-dev-listen-address` with 0.0.0.0 as default prefix.
This means that Vault listener factory [1] bind only on IPv4.

We would like to bind on both IPv4 and IPv6 by default.
net.Listen [1] creates servers which can be bind on both IPv4 and
IPv6 when we provide an empty host address such as ":8200".
