Description

Right now, the container can upload its logs multiple times. Sometimes, containers write different logs into the same log file. After the log aggregation, when we query those logs, it will show:

LogType: stderr
LogContext:

LogType: stdout
LogContext:

LogType: stderr
LogContext:

LogType: stdout
LogContext:

The same files could be displayed multiple times. But we can not figure out which logs come first. We could add extra loguploadedTime to let users have better understanding on the logs.
