Integrate static analysis into CI

[DonatJR]

possibilities:

• Coverty: https://scan.coverity.com/faq#how-get-project-included-in-scan (thanks @bencikpeter for the info)
• VS integrated tools
• ...

Please do not integrate Coverity into the build process right now. It might lead to confusion on their side whether we use the Coverity licence we have for the correct purpose (teaching software security and not for projects that might be considered research projects for which a different licence with a different cost model might apply). We can discuss that later.
