[#328] container/load: Implement RemoteWriterProvider for controller
Define component on app-side that implements RemoteWriterProvider with next logic: * if ServerInfo is nil, call internal dead end provider; * if address in ServerInfo equals to local node's address, do nothing; * otherwise create API client instance via client cache and return the wrapper over it.
