change attributes to bind on ipaddress of node vs 0.0.0.0

there is an issue if you call leader and try to connect to that when the
node is set to bind on 0.0.0.0 the client will get 0.0.0.0 as the leader
address. With this we bind to ipaddress by default which makes it a tad
more sane
update testing to reflect the ip binding.
