level the following APIs, keeping their old routes around as well until 0.4.0
1. datasetio to v1beta: used primarily by eval and training. Given that training is v1alpha, and eval is v1alpha, datasetio is likely to change in structure as real usages of the API spin up. Register,unregister, and iter dataset is sparsely implemented meaning the shape of that route is likely to change.
2. telemetry to v1alpha: telemetry has been going through many changes. for example query_metrics was not even implemented until recently and had to change its shape to work. putting this in v1beta will allow us to fix functionality like OTEL, sqlite, etc. The routes themselves are set, but the structure might change a bit
