Record the actual values for the SQL calls

[dividedmind]

Currently SQL queries are captured without the actual values passed, for example:

    {
      "event": "call",
      "id": 113921,
      "sql_query": {
        "database_type": "H2",
        "sql": "insert into owners (address,city,first_name,last_name,telephone,id) values (?,?,?,?,?,default)"
      },
      "thread_id": 1
    },

Note that the values passed as parameters are not recorded. While the overhead might be prohibitive to enable this in general case, it might be very useful to capture this data to debug specific problems.
