This patch add `--color-diagnostics` to clang-tidy to control colors in diagnostics. With this option, users can force colorful output. This is useful when using clang-tidy with parallelization command line tools (like ninja and GNU parallel), as they often pipe clang-tidy's standard output, which make colors disappear.
