Description

• for each query, generate an unique id.
• the id could describe some context information about the query, like start time, project name, etc.
• for query thread, we could use query id as the name of the thread. As long as user logs thread's name, he can grep query log by query id afterwards.
• pass query id to coprocessor, so that query id gets logged both in query server and region server.
• BadQueryDetector should also log query id
