Notes for Reviewer

This PR creates a separate package for the RouDiEnvironment which does not depend on gTest and can also be build without the tests. This is important for the Rust bindings since they need the RouDi environment for its own tests but not the iceoryx C++ tests which take quite long to build.

Looks good to me, but maybe @dkroenke could have a look at the cmake and bazel files.

I came to the conclusion that it was not one of my brightest moments to add all the committer as reviewer since everybody would think that another one would already review. My new approach is now to ping all the committer in a comment and the ones who like to do the review can add themself as reviewer. I hope this makes it more clear when a PR has sufficient reviewers :)
