#### [alpha] Federated Jobs

Federated Jobs that are automatically deployed to multiple clusters
are now supported. Cluster selection and weighting determine how Job
parallelism and completions are spread across clusters. Federated Job
status reflects the aggregate status across all underlying cluster
jobs.
