> During RU/EU, need a way to bubble up an error of the current item that
> failed. This is useful to quickly get a human-readable error that others UIs
> can quickly retrieve.
> It can print a human-readable error, plus stdout and stderr.
> This would become part of the upgrade endpoint. e.g,
> api/v1/clusters/$name/upgrade_summary/$request_id
> {code}
> {
> attempt_cnt: 1,
> cluster_name: "c1",
> request_id: 1,
> fail_reason: "Failed calling RESTART ZOOKEEPER/ZOOKEEPER_SERVER on host
> c6401.ambari.apache.org",
> // Notice that the rest are inherited from the failed task if it exists.
> command: "CUSTOM_COMMAND",
> command_detail: "RESTART ZOOKEEPER/ZOOKEEPER_SERVER",
> custom_command_name: "RESTART",
> end_time: -1,
> error_log: "/var/lib/ambari-agent/data/errors-1234.txt",
> exit_code: 1,
> host_name: "c6401.ambari.apache.org",
> id: 1234,
> output_log: "/var/lib/ambari-agent/data/output-1234.txt",
> role: "ZOOKEEPER_SERVER",
