Unify pipelines to Validate schemes

[kjezek]

Currently we have tons of pipelines that verify various schemes of Carmen. Since they are all basically the same and they differ only in parametrizing the scheme to run, it should be maintained by one pipeline only that would be itself parameterised.

I started talking to @Lubomir-Jahn about this - he will create a pipeline allowing us to chose which schema we want to run.

Once this is done, we can squash all old schemas (s1-s4/cpp) into one pipeline.
All jobs will run in parallel so there will be no slowdown whatsoever.
