Add --verbose mode for clang-tidy

[georgikoyrushki95]

I was trying to set up clang-tidy for a new repository. I was really struggling to get the compilation database to work and tried so many combinations of things, until I got it up amd running.

The particular issue was I was passing the path to the compile_commands.json file, as opposed to the path to the containing directory. It's clearly set out in the documentation, but it would have saved me a ton of time, if there was an option to turn on debug logs and see what's happening.

Wondering, if that's an easy thing to add for clang-tidy and the other tools in general?
