Description

UI improvement - log streaming.

1. Support partial streaming of logs.
UI doesn't support partial displaying of logs, logs are displayed only when request completes.

2.Current ajax call timeout is 30 sec(except coord logs with action list).
If log fetch request takes more than 30 sec, connection is terminated by UI and logs are never displayed.

Changing it to no timeout. Timeout should be handled by Server.

3.Code reuse : Coord,bundle and WF have their own logic to fetch and display logs.
Adding a function to retrieve and display logs, will be used by all component.

4.For coord job logs, "action list" and "fetch logs" components are on bottom of page, hard to see for user.
Move it to top. Removed refresh button. Logs will be retrieved by "Get logs" button.
