> When you have a ValueProvider<T> that may or may not be accessible at
> construction time, a common task is to wrap it into a single-element
> PCollection<T>. This is especially common when migrating an IO connector that
> used something like Create.of(query) followed by a ParDo, to having query be
> a ValueProvider.
> Currently this is done in an icky way (e.g.
> https://github.com/apache/beam/blob/master/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/datastore/DatastoreV1.java#L615)
> We should have a convenience helper for that.
