config that isn't used

[John A Meinel]

As of fc0869932f1bb06d3353b440bb1d082a63484a49
the charm has a config.yaml with:
options:
  image:
    type: string
    default: "jenkins-agent-operator"
    description: "The docker image to install. Required. Defaults to jenkins-agent-operator from rocks.canonical.com"
  tools:
    type: string
    default: git gcc make bzr
    description: Tooling to deploy on jenkins agent node
  labels:
    type: string
    description: Jenkins labels to associate with jenkins agent node
    default: ""
  jenkins_master_url:
    type: string
    default: ""
    description: |
      Configure the agent to use an explicit jenkins master instead of using
      the jenkins-agent relation. This allows for the agent and master to
      be deployed in different environments.
  jenkins_agent_name:
    type: string
    default: ""
    description: |
      Jenkins agent name that will be seen on the jenkins master.
      Will default to the hostname of the container.
  jenkins_api_token:
    type: string
    default: ""
    description: "Jenkins API token used to join the master"
  jenkins_user:
    type: string
    default: "admin"
    description: "Jenkins user to download agent.jar from master"

However both tools and labels appear to be unused.
It is unclear whether these are carryover from a different charm, and should be pruned, or whether it is intended as desired future use.

Is jenkins_master_url still desirable now that Juju supports cross model relations?
