TODO: Add a Chain progress web View Augment Batch tree-view with Chain data
> [DONE] Tree view w/o Chain will only show Parent/Current batches and Job Counts
> If augmented with Chain data, the above will be annotated with Chain-related info and will be able to show Jobs defined in the Chain
> Chain-jobs will be supplied chain_id and chain_step_id metadata
> Using server-middleware, if a Chain-job (has chain_id and chain_step_id) creates a Batch, tag the Batch w/ the chain_id and chain_step_id
> UI will map Batches to Chain-steps using the chain_step_id. UI will add entries for any Chain-steps that were not tied to a Batch
> [DONE] Use a Lua script to find child batch IDs. Support max_depth, items_per_depth, top_depth_slice parameters
