A service definition must include a `name`, and may optionally provide

an `id`, `tags`, `address`, `port`, and `check`. The `id` is set to the `name` if not
provided. It is required that all services have a unique ID per node, so if names
might conflict then unique ID's should be provided.
The `tags` is a list of opaque value to Consul, but can be used to distinguish
between "master" or "slave" nodes, different versions, or any other service level labels.
The `address` can be used to specify a service specific IP address. By default,
the IP address of the agent is used, and this does not need to be provided.
The `port` can be used as well to make a service oriented architecture
simpler to configure. This way the address and port of a service can
be discovered.
