Description

Post YARN-5742, ATSv2.0 introduces log servlet which could be used for log fetching. Many cluster deployment ATS1.5 may not exist which causes log fetching failure in UI2.

1. UI2 should be able to fetch logs from ATS2.0 log servlet.
2. Its better to take log server url based on the property "yarn.log.server.web-service.url"
3. Each ATSv2 log URL takes clusterid as query params. UI2 should send clusterid query param if required.
