> [HIVE-16334] introduced truncation for storing queries in ZK lock nodes.  This Jira is
to add ellipsis into the query to let the operator know that truncation has occurred and therefore
they will not find the specific query in their logs, only a prefix match will work.
> {code:sql}
> -- Truncation of query may be confusing to operator
> -- Without truncation
> SELECT * FROM TABLE WHERE COL=1
> -- With truncation (operator will not find this query in workload)
> SELECT * FROM TABLE
> -- With truncation (operator will know this is only a prefix match)
> SELECT * FROM TABLE...
> {code}
