Add size labelling to PRs

[amylizzle]

I always like this feature on repos, so we should have it too.
Gotta create the labels tho:

Create the needed labels

Export both GITHUB_TOKEN and REPO (e.g. my-username/my-repository) and run the script below:

for size in XL XXL XS S M L; do
  curl -sf -H "Authorization: Bearer $GITHUB_TOKEN" "https://api.github.com/repos/kubernetes/kubernetes/labels/size/$size" |
    jq '. | { "name": .name, "color": .color, "description": .description }' |
    curl -sfXPOST -d @- -H "Authorization: Bearer $GITHUB_TOKEN" https://api.github.com/repos/$REPO/labels
done

Could we put this, #1664, and conflict-labeler.yml all in one workflow?

No, because #1664 isn't a workflow, it's a GitHub App

What I was wondering is if we could put them in the same file/check.

If not (or it's unusual), I'd like conflict-labeler to have its name changed to something more specific than "Add Extra PR Labels"

I don't actually think I can verify this in any way, but I've tried to combine size and merge conflict labelling. Just the what-files-were-touched one works differently.
