apisix的kafka-logger设置日志格式log_format,不支持单个路由设置

我再进行kafka-logger的log_format设置的时候，一直放到单个路由上进行，发现并不生效，查看官网后发现，这个日志格式只能全局配置。命令如下

http://127.0.0.1:9180/apisix/admin/plugin_metadata/kafka-logger -H 'X-API-KEY: 你的apisix的密码' -X PUT -d '
{
  "log_format": {
	"host": "$host",
	"@timestamp": "$time_iso8601",
	"clientIp": "$remote_addr",
	"routeId": "$route_id",
	"serviceId": "$service_id",
	"requestMethod": "$request_method",
	"requestUri": "$uri",
	"requestQuery": "$query_string",
	"requestSize": "$request_length",
	"responseSize": "$body_bytes_sent",
	"status": "$status",
	"upstreamAddr": "$upstream_addr",
	"upstreamStatus": "$upstream_status",
	"upstreamResponseTime": "$upstream_response_time",
	"requestTime": "$request_time",
	"httpReferer": "$http_referer",
	"startTime": "$msec",
	"httpUserAgent": "$http_user_agent"
  }
}'

无需重启即可生效
