update offset to broker success这个日志输出太多

[王宇]

每次看diamond里面的log，用到mq的pod看日志一次可以打三十几行的：update offset to broker success

而且2～3秒一次，日志一下子就被刷掉了，有没有办法降低info为debug，或者不打印这个update offset to broker success

Set log level by your code:

import (
"github.com/apache/rocketmq-client-go/v2/rlog"
)
.....
	rlog.SetLogLevel("warn")
.....

Or you can set the environment :

export ROCKETMQ_GO_LOG_LEVEL = warn
