An interface to consul:

Key/value storage can be manipulated by read_consul_key/3, update_consul_key/2 and delete_consul_key/1 predicates.
Services can be queried by consul_services/1 and consul_service/2 predicates.
New services can be registered by register_consul_service/4 predicate.
Service can be deregistered by deregister_consul_service/1 predicate.
