Allow triage-ops to use gitlab-triage policy files for real-time triaging
Since we already have policy files in the `triage-ops` project, it would be awesome to reuse these policy files in this project so that we can run the exact same (hygiene) policies, but in real time!
## Ideas for implementation
- The "fetching resources via the API" part of `gitlab-triage` would not be needed since we're directly receiving a resource via the webhook.
- The "conditions" part of the policy would need to be reimplemented in this project, to be checked against the webhook's payload.
- The "actions" part of the policy *could* ideally be reused.
