enableImageStreaming property

If set to true, this container runnable uses Image streaming.

Use Image streaming to allow the runnable to initialize without waiting for the entire container image to download, which can significantly reduce startup time for large container images. When enableImageStreaming is set to true, the container runtime is containerd instead of Docker. Additionally, this container runnable only supports the following container subfields: imageUri, commands[], entrypoint, and volumes[]; any other container subfields are ignored. For more information about the requirements and limitations for using Image streaming with Batch, see the [image-streaming sample on GitHub](https://github.com/GoogleCloudPlatform/batch-samples/tree/main/api-samples/image-streaming).
