Some tools use lineage graph logging to collect query metrics. Currently only query hash is present in this log. Adding query id into it makes such accounting easier. Testing: The equality of query id in the query profile and lineage log is checked in test_lineage.py. A test for TUniqueIdUtil is added to the FE tests.
