/**
 * @module Auth::NamespaceInput
 * Renders the namespace input for the login form. As a user types, the updateNamespace callback fires in the controller to update the query param in the URL.
 * When a namespace is updated, the controller sets `shouldRefocusNamespaceInput = true` which refocuses the input after the route refreshes.
 * For HVD managed clusters the input prepends the administrative namespace: `admin/`. The input is disabled if the url has an OIDC query param: "?o=someprovider"
 *
 * @param {boolean} disabled - determines whether or not the namespace input is disabled
 * @param {function} handleNamespaceUpdate - fires updateNamespace callback in controller
 * @param {string} namespaceQueryParam - namespace query param from the url
 * @param {boolean} shouldRefocusNamespaceInput - if true, refocuses the input on `{{did-insert}}`
