Replace kubeflow-bot with a GitHub App and GitHub Org

[jlewi]

Right now we use a user account
https://github.com/kubeflow-bot
as a robot account.

This is really a pain to manage because there is no easy way to make multiple people administrators of this account.

Using a GitHub App is also much better for programmatic modification.

We can easily create GitHub Apps within our existing Kubeflow GitHub org.

GitHub Apps however can't "own" repositories. So when our CI/CD bot opens up PRs to update kubeflow/manifests where should it create those new branches?

Possible options

1. Use a branch on kubeflow/manifests
2. Create a new GitHub org "kubeflow-bots" and put forks of any repos needed by bots there.

I think I prefer the second option.

• Using a fork seems cleaner then polluting kubeflow repos with a bunch of auto created PRs
• Using separate forks seems like it would require giving the bot less privileges

I created the GitHub App kubeflow-auto-bot

and gave it pull request access. This is needed for #571
