ci: start making integrity checks reusable #13
Description
Current SDK ci comes with many nice integrity patterns that verify integrity (for example that tests exist for each source file etc) of this SDK repository.
However, these checks are not easy to include as keywords into integrity checks of projects using the SDK because some of these checks are implemented as tests and not keywords.
In order to facilitate reuse of integrity checks, the checks have to be separated into 1. robotframework library that implements the keywords 2. the tests that apply these keywords to this particular repository.
In this way, any external project using this SDK will be able to simply reuse the same keywords in project specific integrity checks.
