Update dubbo-samples-api to not use deprecated code
Currently those files are using deprecated call:
AbstractInterfaceConfig::setApplication.
Since those are examples that are used in README.md in dubbo project, it would be nice if they didn't show deprecated code, because it's also not trivial to understand why it's deprecated.
The code itself just uses @Deprecated without any comment whatsoever and there are no examples in README.md that show how that should look. The way I found it was by seeing this issue: https://github.com/apache/dubbo/issues/5679
After this gets updated here, I assume, the same has to be done in https://github.com/apache/dubbo in README.md, maybe in some other places too.
Now, this deprecated code is used all over dubbo-samples, but this submodule seems to be more important, as the code to it is shown as the first thing for people that try to learn and use the framework.
