Navigate Scattered Subworkflows in JMUI

[ruchim]

Today in JMUI, it’s not quite easy to dig into details about a scattered subworkflow. Partially because there’s no UX in Job Manager for splitting out a scatter into its children. This is less consequential for scattered tasks, as one has access to the execution directory quite easily and logs for failed shards.

However, this becomes much more consequential when dealing with scattered subworkflows, as there’s no easy way to access each of the sharded sub-workflows. Instead today, if there is a scattered subworkflow -- it seems like there is a link to one of the sub-workflows, but it seems arbitrarily chosen.

AC: When dealing with a scattered sub-workflow, add functionality expand the scatter into individual components, and treat each sub-workflow as a row in the task details page, with a link out to workflow-level details.

@ruchim Do we still need this or did #641 address it?
