Pulling GitHub into the kernel process

The Repo https://gitlab.kitware.com/utils/rust-ghostflow doesn't have a README.md and it's description is: "Routines which implement various parts of "ghostflow", or the git-hosted workflow.", which basically says "foo implements foo", which isn't helpful to the reader's understanding of what *actually* the purpose of that software is.

So I suggest to link from the description of https://gitlab.kitware.com/utils/rust-ghostflow to https://gitlab.kitware.com/utils/ghostflow-director/, which has minimal info on what ghostflow is, or even better to add a README.md to https://gitlab.kitware.com/utils/rust-ghostflow with minimal info that at least contains that link.
