[cmd] Undeprecate deferredProxy

This changes the way deferred proxy is implemented to not use the deprecated ProxyCommand constructor. This function serves a good purpose that should be kept IMO. The constructor was confusing but this is just good syntactic sugar over `defer(() -> supplier.get().asProxy())`. Signed-off-by: Jade Turner <[email protected]>
