docs: Initializes the parameters and auxiliary states. By default this function
          does nothing. Subclass should override this method if contains parameters.
  
          Parameters
          ----------
          initializer : Initializer
              Called to initialize parameters if needed.
          arg_params : dict
              If not ``None``, should be a dictionary of existing `arg_params`. Initialization
              will be copied from that.
          aux_params : dict
              If not ``None``, should be a dictionary of existing `aux_params`. Initialization
              will be copied from that.
          allow_missing : bool
              If ``True``, params could contain missing values, and the initializer will be
              called to fill those missing params.
          force_init : bool
              If ``True``, will force re-initialize even if already initialized.
          allow_extra : boolean, optional
              Whether allow extra parameters that are not needed by symbol.
              If this is True, no error will be thrown when arg_params or aux_params
              contain extra parameters that is not needed by the executor.
