Description

We can add a tool that can replay commitlogs online.
That may be useful when we restore from some archiving logs without restart the nodes.
I think the tools can have the options like :

1、log name with absolute path if we replay log using local files;
2、only absolute path , so that all file under the dir will be replayed in the order of file list;
3、filter some keys that do not belong to the nodes
4、ratelimit
5、log name and object storage url and bucket , together with information related to authentication，but I think this can be implement in the future.
6、keyspace and table filter, will replay all log data if not specified.
