Prefer `checkstyle.xml` from project folder

[BuZZ-dEE]

If the project (root) folder contains a checkstyle.xml file, automatically prefer that configuration over the global check configurations. "Automatically" so that the user does not need to setup anything despite the installation of the Eclipse Checkstyle plugin.

If the Eclipse Checkstyle plugin is installed in Eclipse and the project root folder contains a checkstyle.xml file, then the Eclipse Checkstyle plugin should automatically load the checkstyle rules from the file to check the code in Eclipse for the project that has the file.

I do not understand what you try to explain to us. Please be more specific.

@romani I updated the issue. Do you have any further questions?

Thanks a lot, can you show bunch of projects that follow this pattern, to let us recognize this trend and support it.

I do not remember this trend.

I even always try to hide tools configs to inner folder to keep root for more critical part

Example: https://github.com/checkstyle/checkstyle/ see folder config with a lot configs for different tools/plugins.
