docstr: Query the traceback of an op.
  
  Args:
    op_name: Name of the op to query.
  
  Returns:
    The traceback of the op, as a list of 3-tuples:
      (filename, lineno, function_name)
  
  Raises:
    ValueError: If the op cannot be found in the tracebacks received by the
      server so far.
