  "message": "Add CallCredentialsProvider and refresh credentials in ByteStreamUploader\n\nUsers may get authentication error in the mid of a long remote build due to credentials timeout. This PR:\n1. Add `CallCredentialsProvider` which can be used by gRPC clients to refresh credentials.\n2. Update `ByteStreamUploader.java` to use the provider and refresh credentials on authentication error.\n\nThe next step would be updating other places where using `CallCrendentials` currently (e.g. `RemoteCacheClient.java`) to use this provider and refresh credentials when necessary.\n\nCloses #12106.\n\nPiperOrigin-RevId: 332394306\n",
