htools: implement post-alloc cluster status display

This patch changes the IAllocator result formatting workflow to return
the final node list, which can be then used to display the final node
status too—currently only the initial status can be shown, which is...

Update node group iallocator design to use job dependencies

While working on a function to submit jobsets, I realized that we

Fix assertion error on unclean master shutdown

Commit 66bd7445 added an assertion to ensure a finalized job has its

htools: update the node-evac/change-group result

… per the new design changes. This also requires changes to
updateEvacSolution, as passing in the original instance is not
