Limit the memory used by the optimizer trace

Details

    Description

      Introduce a new switch optimizer_trace_max_mem_size with default value as 1048576(same as mysql)
      This would imply that the trace would have a memory constraint and we would not write to the trace as soon as we reach this limit.
