feat: add support for temp_bucket, endpoint_config in clusters; add preemptibility for instance group configs (#60)

* feat: Additional fields for the `ClusterConfig` and `InstanceGroupConfig` messages.

This change includes the following updates:
1. There is a new `temp_bucket` field for clusters.
2. There is a new `endpoint_config` field for clusters.
3. There is a new `preemptibility` field for instance group configs.
4. There are various updates to the doc comments.
