Add scripting for releasing to starter

[wtrocki]

I believe now you'll be making similar changes in the charmil-starter repo too

No changes to charmil starter. Let's build script that will do something like this:

mkdir newrepo
cd newrepo
git init 
git remote add starter ...
cp -Rf ../starter ./
git commit -a -m"Starter update"
git push origin main
