            endpoints (list): Endpoints of all the Juju controller units
            user (str): Username for authenticating to the controller
            secret (str): Secret for authenticating to the controller
            cacert (str): Base64 encoded CA certificate for authenticating to the controller
            (optional) pubkey (str): Public key to insert to the charm.
                            This is useful to do `juju ssh`.
                            It is not very useful though.
                            TODO: Test it.
            (optional) lxd-cloud (str): Name of the cloud to use for lxd proxy charms
            (optional) lxd-credentials (str): Name of the lxd-cloud credentials
            (optional) k8s-cloud (str): Name of the cloud to use for k8s proxy charms
            (optional) k8s-credentials (str): Name of the k8s-cloud credentials
            (optional) model-config (n2vc.config.ModelConfig): Config to apply in all Juju models
            (deprecated, optional) api-proxy (str): Proxy IP to reach the controller.
                                                    Used in case native charms cannot react the controller.
