Support multiple pylintrc files

[wsistyrud]

I need 2 different pylintrc files in different directories. However this commit hook only cares about the one in the root of my repository.

.
├── .pylintrc (This should be used for most files in the repository)
├── foo.py
├── subdirectory
│   ├── .pylintrc (This should be used for files in this subdirectory)
│   ├── bar.py

I'm partly working with Robot Framework which requires PascalCase named modules but I don't want that for the other files in my repository.
