A way to sort values by domain name (hyerarchically, so last element first)

Is your feature request related to a problem? Please describe

When I list hostnames I find that sorting by TLD, then second level domain, etc. is better than raw alphabetical sort, as all hosts in the same sub-domain are close together.

Describe the solution you'd like

Right now I'm doing something like this (kinda works but it's limited):

sort_by_label(
    label_replace(
        {query},
       "inv_instance", "$4.$3.$2.$1",
    "instance", "^([^.]+[.])?([^.]+)[.]([^.]+)[.]([^.]+)[-:].*"),
"inv_instance", "instance")

… if it was JavaScript I would probably sort by fqdn.split('.').reverse().join('.'), maybe a specific new sorting function could be added.

Aliaksandr Valialkin suggested a name like sort_by_label_fqdn(q, "label_name").
