Consul does not yet support metadata on services. Spring Cloud's `ServiceInstance` has a `Map<String, String> metadata` field. Spring Cloud Consul uses Consul tags to approximate metadata until Consul officially supports metadata. Tags with the form `key=value` will be split and used as a `Map` key and value respectively. Tags without the equal `=` sign, will be used as both the key and value. fixes gh-162
