* Add a mutable durable dynamicconfig Client Factor the non-file oriented parts of the fileBasedClient into basicClient for reuse (via embed). Then implement a client that can apply updates in threadsafe manner. * Prefer error wrapping in file_based_client Use %w to wrap an error rather than embedding the error string.
