Updated config.pp to add base_path

sensu_rabbitmq_config resource type does not a base_path param being passed to it. This causes it default to /etc/sensu/conf.d which breaks Windows support. Added base_path to resource using $sensu::conf_dir, used on the above file resource to ensure the directory.
