Description

Follow up on HIVE-12338/HIVE-12952, try to improve the WebUI pages for the following areas.

1. For the HiveServer summary page, we can organize the open queries by the sessions. So we will list the sessions and then list the open queries under each session.
2. For each query detailed page, organize the performance page into a meaningful substeps. For compilation stage, probably divided into Parser, optimizer, etc; for runtime stage, seems it's not easy to get the status from yarn, not sure if we can divide further.
3. Metrics dump: better to have a visual display as well as the simple dump.
