Add github-release.py script

[tstellar]

Summary

This script can be used for uploading relases sources and binaries
to github.

My initial thought when I saw the filename was that this was a github version of test-release.sh. Which we'll need too, but it's not this one :-) What do you think about renaming to github-upload-release.py, or something else that has "upload" in the name to make it more explicit?

This is super cool! I just looked at https://github.com/llvm/llvm-project/releases

Should we be using this to host binaries from now on, and link to them from http://releases.llvm.org/ (ah, I see you did this for 7.1.0 already; I guess I'm not keeping up).

Where does one get the $github_token?

If I mess up, is there somewhere I can go to remove files? Does a new upload overwrite old ones?

ultra nit: This blank line seems unnecessary

Rename script and add documentation for how to obtain a github token.

Yes, I experimented with this for 7.1.0 and also 8.0.1-rc*. It seems to work well, and I think it makes sense to do this for all releases going forward. It will save the LLVM Foundation bandwidth costs and we need a new place to store the binaries anyway once SVN goes away.

Looks good to me!
