Batch semver compliant upgrades and have individual PRs for major updates

[bencooper222]

Most of our dependency specifications allow for minor/patch upgrades with no fuss - we just merge those PRs in right away, trusting that it'll be ok based on the maintainers judgement.

However, we want to give a bit more scrutiny to major (breaking) changes. Ideally, we would like all semver compliant upgrades to come in batched every week or so (configurable) while major upgrades each get their own PR that we can analyze ourselves.

That's great feedback, thanks @bencooper222!
