Scenario VMTasks.boot_runcommand_delete now can populate report tab "Scenario Data" with any allowed charts. SSH command return value structure new reflects Scenario.add_output() arguments. Also, there is new shell script samples/tasks/support/instance_test.sh which generates different load on server and creates proper JSON output. Old format of command output is also supported but marked as deprecated. Change-Id: I6a34b634ea7d9080f9ca08bf0f82d04fa69406d9
