Import prometheus chart source code from stable repo with git history

[scottrigby]

Quick how-to, to increase the bus factor:

1. Bring down the stable charts code

   git clone git@github.com:helm/charts.git prometheus-helm-charts/
   cd prometheus-helm-charts/
   

2. Filter only prometheus charts and rename stable dir to charts while retaining direct commit history all in one go, with git-filter-repo

   brew install git-filter-repo
   git filter-repo --path-glob 'stable/prometheus*' --path-rename stable/:charts/
   

3. If you want to adopt main instead of master branch naming, do it now. See Change master branch to main #6

   git checkout -b main
   git branch -D master
   

4. Set the remote and push. See Transfer ownership and rename scottrigby/prometheus-helm-charts to prometheus-community/helm-charts #11 for context

   git remote add origin git@github.com:scottrigby/prometheus-helm-charts.git
   git push -u origin main
