Added Duo Code Review automated exclusion

Phil Hughesrequested to merge
ph/duoCodeReviewAutomatedRules into master

What does this MR do and why?

Added a new resolver that parses a mr-review-automated-rules.yaml file in the project or the projects ancestor groups if the group has a selected project for the Duo Code Review instructions.

The YML file will look like:

exclude:
  authors:
    - renovate-bot
    - dependabot
    - "*-bot"
    - "bot-*"

  source_branches:
    - "renovate/*"
    - "dependabot/*"
    - "auto-update/*"

  target_branches:
    - "feature/*"
    - "spike/*"
    - "wip/*"

This then stops the Duo Code review user being automatically assigned to merge requests that match any of that data. Users can still assign the Duo Code review users themselves to start the review.
