A special broker type where the outputs are identified by unique labels and can be created, changed and removed during runtime via a REST API.

# Config fields, showing default values
label: ""
outputs: {}
prefix: ""
timeout: 5s
max_in_flight: 1

The broker pattern used is always fan_out, meaning each message will be delivered to each dynamic output.

To GET a JSON map of output identifiers with their current uptimes use the '/outputs' endpoint.

To perform CRUD actions on the outputs themselves use POST, DELETE, and GET methods on the /outputs/{output_id} endpoint. When using POST the body of the request should be a YAML configuration for the output, if the output already exists it will be changed.
