Get the removed_rsrc_list for each ResourceGroup in the stack.
When building the instances list, add entries with 'provisioned': false
if the current index is in removed_rsrc_list and no replacement using
the same hostname exist.
We no longer sort entries from AnsibleHostVarsMap, I think sorting might
actually be problematic in a corner case where HostnameMap was used to
give nodes non-sort friendly names like:
overcloud-controller-0: non
overcloud-controller-1: sort
overcloud-controller-2: friendly
Sorting ^^ would result:
overcloud-controller-0: friendly
overcloud-controller-1: non
overcloud-controller-2: sort
