Description

Although we copy the whole log files from taskmanager to blob service host, sometimes we may not be able to read the whole file's content on WebUI because of the browser's load.
We already use RandomAccessFile to read files, so I think we need to support read the log file from any row of it by adding a parameter at the end of url like http://xxx/#/taskmanager/container_xx/log/100.
