use get and set for WorkChain settings

[superstar54]

The get_configuration_parameters method of ConfigureQeAppWorkChainStep is hard coded. In principle, it should only need to call the method from sub-settings (plugin's panel). e.g

        workchain_settings = self.workchain_settings.get_setting_parameters()
        advanced_settings = self.advanced_settings.get_setting_parameters()

Same for the setting method.
In this PR, I make this change for the WorkChainSettings. Next PR will be the AdvancedSettings.

Thanks! Then, I will merge this first. Because the change in the advanced setting will be a little bit complicated, it is better to add it in another PR.
