Link via an ambassador container

Rather than hardcoding network links between a service consumer and provider, Docker encourages service portability, for example instead of:

(consumer) --> (redis)

(consumer) --> (redis-ambassador) ---network---> (redis-ambassador) --> (redis)

When you need to rewire your consumer to talk to a different Redis server, you can just restart the redis-ambassador container that the consumer is connected to.

This pattern also allows you to transparently move the Redis server to a different docker host from the consumer.

Using the svendowideit/ambassador container, the link wiring is controlled entirely from the do
