optional branch protection settings

[omercnet]

I wish to have an org wide branch protection rules, requiring all repos to have basic branch protection, it would ideally look something like this:

branches:
  - name: master
    # Branch Protection settings. Set to null to disable
    protection:
      required_pull_request_reviews:
        required_approving_review_count: 1
        dismiss_stale_reviews: true
        require_code_owner_reviews: true
      enforce_admins: true
      required_linear_history: true

but based on #150 this won't be applied because some settings are missing, specifically the required_status_checks setting.

my ask is, that missing settings will simply be ignored or patched to existing settings, so by settings this at the org level, it would allow customizing checks for each repo but not removing the org level requirements of reviews, enforce admins, etc.
