Minimum Viable Product (MVP)

Express your minimal viable product in the form of
the Ansible DOCUMENTATION block format:

module: services_unbound_blocklist
short_description: Configuration of Unbound blocklists.

    type: bool
    required: true
    default: false
  predefined_blocklists:
    description: 
      - "Select which predeifined DNSBL you want to use."
      - "See https://docs.opnsense.org/manual/unbound.html#predefined-sources for detailed source description"
    type: list
    elements: str

The types and values should be implemented according to the OPNsense core code:
