Added OWASP Dependency Check

See #512 where the discussion around vulnerabilities should be kept.

I don‘t know how exactly you want to integrate this into your build and we should add the plugin to Maven as well (although I personally don‘t understand why this project uses Gradle and Maven).

Initially project used Maven and had half-working Gradle configuration. Now we are migrating project to use Gradle only.

Adding it only to Gradle setup is ok, as currently both Maven and Gradle builds run on CI.

Is there anything more you'd like to do with this PR?

[Fleshgrinder]

@shashachu gauge your interest in adding it and ideas on how to add it to CI. Once we have the latter I'd change it from a draft to a PR.
