// QueryFeature makes a request for instructions on how to enable a
// feature, such as Funnel, for the node's tailnet.
//
// This request itself does not directly enable the feature on behalf
// of the node, but rather returns information that can be presented
// to the acting user about where/how to enable the feature.
//
// If relevant, this includes a control URL the user can visit to
// explicitly consent to using the feature. LocalClient.WatchIPNBus
// can be used to block on the feature being enabled.
//
// 2023-08-02: Valid feature values are "serve" and "funnel".
