Overview: deprecate existing Talos resource API, and introduce new COSI API. Consequences: * COSI API can only go via one-2-one proxy (`client.WithNode`) * client-side API access is way easier with `state.State` wrappers * lots of small changes on the client side to use new APIs Signed-off-by: Andrey Smirnov <andrey.smirnov@talos-systems.com>
