This commit adds query endtime to impalad's lineage log entries consumed
by navigator. The lineage graph is constructed in the frontend and is then
passed to the backend as a serialized thrift object. When the query terminates
(includes cancellations and aborts), the backend appends the query endtime
("endTime") to the lineage graph and generates the lineage log entry in
JSON format.
