no issue
- the `config:base` preset sets a maximum of 2 PRs per hour
- we have specific timings for Renovate in this repo so the max limit is more hindrance than help
no issue
- ignore `ember-exam` until it's compatible with latest stable of `ember-mocha`
- see https://github.com/ember-cli/ember-exam/issues/238
- moved `ember-exam`, `ember-mocha`, and `testem` into their own group so changes to test env don't cause addon upgrade PRs to fail
