integrate clang-tidy with v1 build

[thirtytwobits]

run clang-tidy at build-time.

Clang-Tidy should be integrated via CXX_CLANG_TIDY and Sonar needs to be invoked on pull request builds or when the commit is tagged with #sonar.

@serges147 I would like to prioritize this because the way the codebase is now we're already going to have to go back and modify it to make Clang-Tidy and Sonar accept it.

@pavel-kirienko Pavel, I'm right that I can use exactly the same approach as in CETL in terms of Sonar? Also where to get clang-tidy config file?

1. Yes; alternatively, you could use Dyshlo as a reference.
2. Let's start with this one (it may require some tweaking but we'll get to that later):
