Pull request description:

  Demo of integrating the [bitcoin-tidy](https://github.com/theuni/bitcoin-tidy-plugin), [clang-tidy plugin](https://clang.llvm.org/extra/clang-tidy/) written by theuni into our tidy CI job.

  The plugin currently has a single check, `bitcoin-unterminated-logprintf`. This would replace our current Python driven, `git-grep`-based, `.cpp` file only, lint-logs linter.
