Vasil remove remote evals

@skaapgif It seems that last time I sent this pull request to the gamechanger/nodeload instead of edgecampus/nodeload. I am correcting myself on that one.

With this changes the library should be usable to us. The critical eval have been removed and we can specify test scenarios via environment variable, so that the slaves can see them.

I have also created a development branch in our forked repository so that we can keep any changes there. I don't want to merge them in master, since the changes will break interface compatibility with the original project.
