> As the job running, the log files are becoming large.
> Current log api returns all contents，it will block or not work when file is large.It's unfriendly for user.
> As application runs on jvm, sometime user need see log of gc, but there aren't this contents.
> Above all, we need new apis:
>  *  list taskmanager all log file
>  ** /taskmanagers/taskmanagerid/logs
>  ** 
> {code:java}
> {
>   "logs": [
>     {
>       "name": "taskmanager.log",
>       "size": 12529
>     }
>   ]
> } {code}
>  * see taskmanager log file by range
>  ** /taskmanagers/taskmanagerid/logs/:filename?start=[start]&count=[count]
>  ** 
> {code:java}
>  {
>     "data": "logcontent",
>     "file_size": 342882
>  }
> {code}
>  * list jobmanager all log file
>  ** /jobmanager/logs
>  ** 
> {code:java}
> {
>   "logs": [
>     {
>       "name": "jobmanager.log",
>       "size": 12529
>     }
>   ]
> }
> {code}
>  * see jobmanager log file by range
>  ** /jobmanager/logs/:filename?start=[start]&count=[count]
>  ** 
> {code:java}
> {
>   "data": "logcontent",
>   "file_size": 342882

> {code}
