Describe the proposed behavior

some script / flow that (given some GH credentials) in cookbook/ that's triggered by the creation of a PR from dependabot that also accepts some heuristics from the user on what dependabot should merge.

the script should produce some numerical confidence that the PR should be merged and:

• merge if very confident that it should be merged based on heuristics
• notify maintainer for resolution if unsure (or do nothing)
• close if sure it should not be merged based on heuristics
