NatsAddr of a task is 0.0.0.0

When BindAddr is 0.0.0.0 and AdvertiseAddr.Nats is correctly set,

• NatsAddr passed to task (for nats client to connect) is 0.0.0.0
• while NatsAddr for nats server is correct

Problem

• a.config.AdvertiseAddrs.Nats should be used instead of a.config.BindAddr

TODO

• review this

conf.Node.HTTPAddr = fmt.Sprintf("%s:%d", a.config.BindAddr, a.config.Ports.HTTP)
