[kudu-CR] [Client] Add query id to trace the whole query process

["Wang Xixu (Code Review)" <ge...@cloudera.org>]

Hello Mahesh Reddy, Tidy Bot, Jian Zhang, Yuqi Du, Yingchun Lai, Yifan Zhang, Kudu Jenkins, Abhishek Chennaka, 

I'd like you to reexamine a change. Please visit

    http://gerrit.cloudera.org:8080/18846

to look at the new patch set (#23).

Change subject: [Client] Add query id to trace the whole query process
......................................................................

[Client] Add query id to trace the whole query process

Impala uses Kudu client library to query Kudu. But it is
difficult to trace the whole query process. In Kudu tablet
server, it only uses scanner id to trace the reading of one
tablet.

In this patch, Impala can post parameter: query id to Kudu
Kudu tablet server will trace any reading of any tablet with
query id. That is convenient to debug problem.
