This patch adds process start time and version to the /backends page. Two more optional elements are added in BackendDescriptorPB and can be broadcast through statestore topic. This information should be helpful for users checking all backends in a large cluster. For display, as two more columns are added to the table of backend information, the table is changed to 'table-responsive' to be scrolled horizontally with ease. A sample screenshot is attached to the IMPALA-12096 ticket. Testing: - Added cases to test_web_pages.py Change-Id: I5f1f0ba0081986f428840442c247d7dde9e1ba05 Reviewed-on: http://gerrit.cloudera.org:8080/19800 Reviewed-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com> Tested-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com>
