Describe the solution you've chosen

Implements the flow from chdsbd/kodiak#701 (comment)

1. Sets Kodiak to auto merge renovate patch and minor updates. Kodiak will sync those with the default branch before merging.
2. Tells renovate not to auto merge those, so those PRs don't skip the PRs queue.
3. Tells renovate to rebase PRs only when they are conflicted (instead when the are 1 commit behind the default branch).

Describe alternatives you've considered

Letting renovate rebase+automerge and waste CI resources.
