Make it possible for a aec-plugin to provide props/params through module-echo-cancel and make it possible for a aec-plugin to listen and react to these props/params getting updated. Add method enum_props() that is used under setup_streams() to get props from aec_plugin. Add get_params() and set_params() for updating and getting aec-plugin params under the input/output_param_changed calls and getting params under setup_streams().
