FakeStorageRpc/LocalStorageHelper: leads to logs about needing to call Builder#setApplicationName

[glasser]

Steps to reproduce

1. Use LocalStorageHelper at all
2. See log messages needing to call setApplicationName

Code example

Anything using LocalStorageHelper, eg

LocalStorageHelper.customOptions(true).getService().writer(...)

ends up running this code in FakeStorageRpc.java

  public com.google.api.services.storage.Storage getStorage() {
    HttpTransport transport = new FakeStorageRpcHttpTransport();
    HttpRequestInitializer httpRequestInitializer = request -> {};
    return new com.google.api.services.storage.Storage(
        transport, new GsonFactory(), httpRequestInitializer);
  }

This Storage constructor creates and then immediately uses a Storage.Builder, which means there's no place to call Builder#setApplicationName, leading to an unavoidable log.

Stack trace

The logged message is:

WARN  com.google.api.client.googleapis.services.AbstractGoogleClient  - Application name is not set. Call Builder#setApplicationName.
