List expansion for labels

We want to add team labels to issues without team labels, based on the feature labels. Some list could be found at gitlab-org/quality/triage-ops#59 (comment 112116993)

A proposal to do this is adding brace expansion, similar to https://gitlab.com/gitlab-org/gitlab-triage/merge_requests/44

It'll look like:

      - name: Label ~Manage for issues with Manage features
        conditions:
          state: opened
          forbidden_labels:
            - Manage
          labels:
            - {user management, user profile, analytics, cycle analytics, ...}
        actions:
          labels:
            - Manage
